The remote host is affected by the vulnerability described in GLSA-201312-03 (OpenSSL: Multiple Vulnerabilities)

    Multiple vulnerabilities have been discovered in OpenSSL. Please review       the CVE identifiers referenced below for details.
  Impact :

    Remote attackers can determine private keys, decrypt data, cause a       Denial of Service or possibly have other unspecified impact.
  Workaround :

    There is no known workaround at this time.

openssl was updated to 1.0.0k security release to fix bugs and security issues. (bnc#802648 bnc#802746) The version was upgraded to avoid backporting the large fixes for SSL, TLS and DTLS Plaintext Recovery Attack (CVE-2013-0169) TLS 1.1 and 1.2 AES-NI crash (CVE-2012-2686) OCSP invalid key DoS issue (CVE-2013-0166)

Also the following bugfix was included: bnc#757773 - c_rehash to accept more filename extensions

openssl was updated to 1.0.1e, fixing bugs and security issues :

o Fix renegotiation in TLS 1.1, 1.2 by using the correct TLS version. o Include the fips configuration module. o Fix OCSP bad key DoS attack CVE-2013-0166 bnc#802746 o Fix for SSL/TLS/DTLS CBC plaintext recovery attack CVE-2013-0169 bnc#802184 o Fix for TLS AESNI record handling flaw CVE-2012-2686

Also the following buyg was fixed: bnc#757773 - c_rehash to accept more filename extensions

OpenSSL security team reports :

A flaw in the OpenSSL handling of CBC mode ciphersuites in TLS 1.1 and TLS 1.2 on AES-NI supporting platforms can be exploited in a DoS attack.

A flaw in the OpenSSL handling of OCSP response verification can be exploited in a denial of service attack.

USN-1732-1 fixed vulnerabilities in OpenSSL. The fix for CVE-2013-0166 and CVE-2012-2686 introduced a regression causing decryption failures on hardware supporting AES-NI. This update temporarily reverts the security fix pending further investigation. We apologize for the inconvenience.

Adam Langley and Wolfgang Ettlingers discovered that OpenSSL incorrectly handled certain crafted CBC data when used with AES-NI. A remote attacker could use this issue to cause OpenSSL to crash, resulting in a denial of service. This issue only affected Ubuntu 12.04 LTS and Ubuntu 12.10. (CVE-2012-2686)

Nadhem Alfardan and Kenny Paterson discovered that the TLS protocol as used in OpenSSL was vulnerable to a timing side-channel attack known as the 'Lucky Thirteen' issue. A remote attacker could use this issue to perform plaintext-recovery attacks via analysis of timing data.
(CVE-2013-0169).

Note that Tenable Network Security has extracted the preceding description block directly from the Ubuntu security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

Updated rhevm-spice-client packages that fix multiple security issues are now available for Red Hat Enterprise Virtualization Manager 3.

The Red Hat Security Response Team has rated this update as having Important 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.

Red Hat Enterprise Virtualization Manager provides access to virtual machines using SPICE. These SPICE client packages provide the SPICE client and usbclerk service for both Windows 32-bit operating systems and Windows 64-bit operating systems.

The rhevm-spice-client package includes the mingw-virt-viewer Windows SPICE client. OpenSSL, a general purpose cryptography library with a TLS implementation, is bundled with mingw-virt-viewer. The mingw-virt-viewer package has been updated to correct the following issues :

An information disclosure flaw was found in the way OpenSSL handled TLS and DTLS Heartbeat Extension packets. A malicious TLS or DTLS client or server could send a specially crafted TLS or DTLS Heartbeat packet to disclose a limited portion of memory per request from a connected client or server. Note that the disclosed portions of memory could potentially include sensitive information such as private keys.
(CVE-2014-0160)

It was discovered that OpenSSL leaked timing information when decrypting TLS/SSL and DTLS protocol encrypted records when CBC-mode cipher suites were used. A remote attacker could possibly use this flaw to retrieve plain text from the encrypted packets by using a TLS/SSL or DTLS server as a padding oracle. (CVE-2013-0169)

A NULL pointer dereference flaw was found in the way OpenSSL handled TLS/SSL protocol handshake packets. A specially crafted handshake packet could cause a TLS/SSL client using OpenSSL to crash.
(CVE-2013-4353)

It was discovered that the TLS/SSL protocol could leak information about plain text when optional compression was used. An attacker able to control part of the plain text sent over an encrypted TLS/SSL connection could possibly use this flaw to recover other portions of the plain text. (CVE-2012-4929)

Red Hat would like to thank the OpenSSL project for reporting CVE-2014-0160. Upstream acknowledges Neel Mehta of Google Security as the original reporter.

The updated mingw-virt-viewer Windows SPICE client further includes OpenSSL security fixes that have no security impact on mingw-virt-viewer itself. The security fixes included in this update address the following CVE numbers :

CVE-2013-6449, CVE-2013-6450, CVE-2012-2686, and CVE-2013-0166

All Red Hat Enterprise Virtualization Manager users are advised to upgrade to these updated packages, which address these issues.
