The rhev-hypervisor5 package provides a Red Hat Enterprise Virtualization Hypervisor ISO disk image. The Red Hat Enterprise Virtualization Hypervisor is a dedicated Kernel-based Virtual Machine (KVM) hypervisor. It includes everything necessary to run and manage virtual machines: A subset of the Red Hat Enterprise Linux operating environment and the Red Hat Enterprise Virtualization Agent.

Note: Red Hat Enterprise Virtualization Hypervisor is only available for the Intel 64 and AMD64 architectures with virtualization extensions.

A heap overflow flaw was found in the way QEMU-KVM emulated the e1000 network interface card. A privileged guest user in a virtual machine whose network interface is configured to use the e1000 emulated driver could use this flaw to crash the host or, possibly, escalate their privileges on the host. (CVE-2012-0029)

A divide-by-zero flaw was found in the Linux kernel's igmp_heard_query() function. An attacker able to send certain IGMP (Internet Group Management Protocol) packets to a target system could use this flaw to cause a denial of service. (CVE-2012-0207)

A double free flaw was discovered in the policy checking code in OpenSSL. A remote attacker could use this flaw to crash an application that uses OpenSSL by providing an X.509 certificate that has specially crafted policy extension data. (CVE-2011-4109)

An information leak flaw was found in the SSL 3.0 protocol implementation in OpenSSL. Incorrect initialization of SSL record padding bytes could cause an SSL client or server to send a limited amount of possibly sensitive data to its SSL peer via the encrypted connection. (CVE-2011-4576)

It was discovered that OpenSSL did not limit the number of TLS/SSL handshake restarts required to support Server Gated Cryptography. A remote attacker could use this flaw to make a TLS/SSL server using OpenSSL consume an excessive amount of CPU by continuously restarting the handshake. (CVE-2011-4619)

OpenSSL is a toolkit that implements the Secure Sockets Layer (SSL v2/v3) and Transport Layer Security (TLS v1) protocols, as well as a full-strength, general purpose cryptography library.

It was discovered that the Datagram Transport Layer Security (DTLS) protocol implementation in OpenSSL leaked timing information when performing certain operations. A remote attacker could possibly use this flaw to retrieve plain text from the encrypted packets by using a DTLS server as a padding oracle. (CVE-2011-4108)

A double free flaw was discovered in the policy checking code in OpenSSL. A remote attacker could use this flaw to crash an application that uses OpenSSL by providing an X.509 certificate that has specially crafted policy extension data. (CVE-2011-4109)

An information leak flaw was found in the SSL 3.0 protocol implementation in OpenSSL. Incorrect initialization of SSL record padding bytes could cause an SSL client or server to send a limited amount of possibly sensitive data to its SSL peer via the encrypted connection. (CVE-2011-4576)

It was discovered that OpenSSL did not limit the number of TLS/SSL handshake restarts required to support Server Gated Cryptography. A remote attacker could use this flaw to make a TLS/SSL server using OpenSSL consume an excessive amount of CPU by continuously restarting the handshake. (CVE-2011-4619)

All OpenSSL users should upgrade to these updated packages, which contain backported patches to resolve these issues. For the update to take effect, all services linked to the OpenSSL library must be restarted, or the system rebooted.

According to its self-reported version number, the remote Junos Space version is prior to 14.1R1. It is, therefore, affected by multiple vulnerabilities in bundled third party software components :

  - Multiple vulnerabilities in the bundled OpenSSL CentOS     package. (CVE-2011-4109, CVE-2011-4576, CVE-2011-4619,     CVE-2012-0884, CVE-2012-2110, CVE-2012-2333,     CVE-2013-0166, CVE-2013-0169, CVE-2014-0224)

  - Multiple vulnerabilities in Oracle MySQL.
    (CVE-2013-5908)

  - Multiple vulnerabilities in the Oracle Java runtime.
    (CVE-2014-0411, CVE-2014-0423, CVE-2014-4244,     CVE-2014-0453, CVE-2014-0460, CVE-2014-4263,     CVE-2014-4264)

Multiple vulnerabilities has been found and corrected in openssl :

The DTLS implementation in OpenSSL before 0.9.8s and 1.x before 1.0.0f performs a MAC check only if certain padding is valid, which makes it easier for remote attackers to recover plaintext via a padding oracle attack (CVE-2011-4108).

Double free vulnerability in OpenSSL 0.9.8 before 0.9.8s, when X509_V_FLAG_POLICY_CHECK is enabled, allows remote attackers to have an unspecified impact by triggering failure of a policy check (CVE-2011-4109).

The SSL 3.0 implementation in OpenSSL before 0.9.8s and 1.x before 1.0.0f does not properly initialize data structures for block cipher padding, which might allow remote attackers to obtain sensitive information by decrypting the padding data sent by an SSL peer (CVE-2011-4576).

The Server Gated Cryptography (SGC) implementation in OpenSSL before 0.9.8s and 1.x before 1.0.0f does not properly handle handshake restarts, which allows remote attackers to cause a denial of service via unspecified vectors (CVE-2011-4619).

The updated packages have been patched to correct these issues.

Various security vulnerabilities have been fixed in OpenSSL :

  - DTLS plaintext recovery attack. (CVE-2011-4108)

  - double-free in Policy Checks. (CVE-2011-4109)

  - uninitialized SSL 3.0 padding. (CVE-2011-4576)

  - malformed RFC 3779 data can cause assertion failures.
    (CVE-2011-4577)

  - SGC restart DoS attack (CVE-2011-4619)

Updated openssl packages that fix multiple security issues are now available for Red Hat Enterprise Linux 5.

The Red Hat Security Response Team has rated this update as having moderate security impact. Common Vulnerability Scoring System (CVSS) base scores, which give detailed severity ratings, are available for each vulnerability from the CVE links in the References section.

The remote VMware ESXi 5.0 host is affected by Multiple Vulnerabilities :

  - An integer overflow condition exists in the
    __tzfile_read() function in the glibc library. An     unauthenticated, remote attacker can exploit this, via     a crafted timezone (TZ) file, to cause a denial of     service or the execution of arbitrary code.
    (CVE-2009-5029)

  - ldd in the glibc library is affected by a privilege     escalation vulnerability due to the omission of certain     LD_TRACE_LOADED_OBJECTS checks in a crafted executable     file. Note that this vulnerability is disputed by the     library vendor. (CVE-2009-5064)

  - A remote code execution vulnerability exists in the     glibc library due to an integer signedness error in the     elf_get_dynamic_info() function when the '--verify'     option is used. A remote attacker can exploit this by     using a crafted ELF program with a negative value for a     certain d_tag structure member in the ELF header.
    (CVE-2010-0830)

  - A flaw exists in OpenSSL due to a failure to properly     prevent modification of the ciphersuite in the session     cache when SSL_OP_NETSCAPE_REUSE_CIPHER_CHANGE_BUG is     enabled. A remote attacker can exploit this to force a     downgrade to an unintended cipher by intercepting the     network traffic to discover a session identifier.
    (CVE-2010-4180)

  - A flaw exists in OpenSSL due to a failure to properly     validate the public parameters in the J-PAKE protocol     when J-PAKE is enabled. A remote attacker can exploit     this, by sending crafted values in each round of the     protocol, to bypass the need for knowledge of the shared     secret. (CVE-2010-4252)

  - A out-of-bounds memory error exists in OpenSSL that     allows a remote attacker to cause a denial of service or     possibly obtain sensitive information by using a     malformed ClientHello handshake message. This is also     known as the 'OCSP stapling vulnerability'.
    (CVE-2011-0014)

  - A flaw exists in the addmntent() function in the glibc     library due to a failure to report the error status for     failed attempts to write to the /etc/mtab file. A local     attacker can exploit this to corrupt the file by using     writes from a process with a small RLIMIT_FSIZE value.
    (CVE-2011-1089)

  - A flaw exists in the png_set_text_2() function in the     file pngset.c in the libpng library due to a failure to     properly allocate memory. An unauthenticated, remote     attacker can exploit this, via a crafted text chunk in a     PNG image file, to trigger a heap-based buffer overflow,     resulting in denial of service or the execution of     arbitrary code. (CVE-2011-3048)

  - A flaw exists in the DTLS implementation in OpenSSL due     to performing a MAC check only if certain padding is     valid. A remote attacker can exploit this, via a padding     oracle attack, to recover the plaintext. (CVE-2011-4108)

  - A double-free error exists in OpenSSL when the     X509_V_FLAG_POLICY_CHECK is enabled. A remote attacker     can exploit this by triggering a policy check failure,     resulting in an unspecified impact. (CVE-2011-4109)

  - A flaw exists in OpenSSL in the SSL 3.0 implementation     due to improper initialization of data structures used     for block cipher padding. A remote attacker can exploit     this, by decrypting the padding data sent by an SSL     peer, to obtain sensitive information. (CVE-2011-4576)

  - A denial of service vulnerability exists in OpenSSL when     RFC 3779 support is enabled. A remote attacker can     exploit this to cause an assertion failure, by using an     X.509 certificate containing certificate extension data     associated with IP address blocks or Autonomous System     (AS) identifiers. (CVE-2011-4577)

  - A denial of service vulnerability exists in the RPC     implementation in the glibc library due to a flaw in the     svc_run() function. A remote attacker can exploit this,     via large number of RPC connections, to exhaust CPU     resources. (CVE-2011-4609)

  - A denial of service vulnerability exists in the Server     Gated Cryptography (SGC) implementation in OpenSSL due     to a failure to properly handle handshake restarts. A     remote attacker can exploit this, via unspecified     vectors, to exhaust CPU resources. (CVE-2011-4619)

  - A denial of service vulnerability exists in OpenSSL due     to improper support of DTLS applications. A remote     attacker can exploit this, via unspecified vectors     related to an out-of-bounds read error. Note that this     vulnerability exists because of an incorrect fix for     CVE-2011-4108. (CVE-2012-0050)

  - A security bypass vulnerability exists in the glibc     library due to an integer overflow condition in the     vfprintf() function in file stdio-common/vfprintf.c. An     attacker can exploit this, by using a large number of     arguments, to bypass the FORTIFY_SOURCE protection     mechanism, allowing format string attacks or writing to     arbitrary memory. (CVE-2012-0864)

  - A denial of service vulnerability exists in the glibc     library in the vfprintf() function in file     stdio-common/vfprintf.c due to a failure to properly     calculate a buffer length. An attacker can exploit this,     via a format string that uses positional parameters and     many format specifiers, to bypass the FORTIFY_SOURCE     format-string protection mechanism, thus causing stack     corruption and a crash. (CVE-2012-3404)

  - A denial of service vulnerability exists in the glibc     library in the vfprintf() function in file     stdio-common/vfprintf.c due to a failure to properly     calculate a buffer length. An attacker can exploit this,     via a format string with a large number of format     specifiers, to bypass the FORTIFY_SOURCE format-string     protection mechanism, thus triggering desynchronization     within the buffer size handling, resulting in a     segmentation fault and crash. (CVE-2012-3405)

  - A flaw exists in the glibc library in the vfprintf()     function in file stdio-common/vfprintf.c due to a     failure to properly restrict the use of the alloca()     function when allocating the SPECS array. An attacker     can exploit this, via a crafted format string using     positional parameters and a large number of format     specifiers, to bypass the FORTIFY_SOURCE format-string     protection mechanism, thus triggering a denial of     service or the possible execution of arbitrary code.
    (CVE-2012-3406)

  - A flaw exists in the glibc library due to multiple     integer overflow conditions in the strtod(), strtof(),     strtold(), strtod_l(), and other unspecified related     functions. A local attacker can exploit these to trigger     a stack-based buffer overflow, resulting in an     application crash or the possible execution of arbitrary     code. (CVE-2012-3480)

  - A privilege escalation vulnerability exists in the     Virtual Machine Communication Interface (VMCI) due to a     failure by control code to properly restrict memory     allocation. A local attacker can exploit this, via     unspecified vectors, to gain privileges. (CVE-2013-1406)

  - An error exists in the implementation of the Network     File Copy (NFC) protocol. A man-in-the-middle attacker     can exploit this, by modifying the client-server data     stream, to cause a denial of service or the execution     of arbitrary code. (CVE-2013-1659)

The version of OpenSSL running on the remote host is affected by the following vulnerabilities :

  - The DTLS implementation in OpenSSL before 0.9.8s and 1.x     before 1.0.0f performs a MAC check only if certain     padding is valid, which makes it easier for remote     attackers to recover plaintext via a padding oracle     attack. (CVE-2011-4108)

  - Double free vulnerability in OpenSSL 0.9.8 before     0.9.8s, when X509_V_FLAG_POLICY_CHECK is enabled, allows     remote attackers to have an unspecified impact by     triggering failure of a policy check. (CVE-2011-4109)

  - The SSL 3.0 implementation in OpenSSL before 0.9.8s and     1.x before 1.0.0f does not properly initialize data     structures for block cipher padding, which might allow     remote attackers to obtain sensitive information by     decrypting the padding data sent by an SSL peer.
    (CVE-2011-4576)

  - The Server Gated Cryptography (SGC) implementation in     OpenSSL before 0.9.8s and 1.x before 1.0.0f does not     properly handle handshake restarts, which allows remote     attackers to cause a denial of service via unspecified     vectors. (CVE-2011-4619)

  - OpenSSL 0.9.8s and 1.0.0f does not properly support DTLS     applications, which allows remote attackers to cause a     denial of service via unspecified vectors. NOTE: this     vulnerability exists because of an incorrect fix for     CVE-2011-4108. (CVE-2012-0050)

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

  - Double free vulnerability in OpenSSL 0.9.8 before 0.9.8s, when X509_V_FLAG_POLICY_CHECK is enabled, allows     remote attackers to have an unspecified impact by triggering failure of a policy check. (CVE-2011-4109)

Note that Nessus relies on the presence of the package as reported by the vendor.
