From Red Hat Security Advisory 2009:1550 :

Updated kernel packages that fix several security issues and multiple bugs are now available for Red Hat Enterprise Linux 3.

This update has been rated as having important security impact by the Red Hat Security Response Team.

The kernel packages contain the Linux kernel, the core of any Linux operating system.

Security fixes :

* when fput() was called to close a socket, the __scm_destroy() function in the Linux kernel could make indirect recursive calls to itself. This could, potentially, lead to a denial of service issue.
(CVE-2008-5029, Important)

* the sendmsg() function in the Linux kernel did not block during UNIX socket garbage collection. This could, potentially, lead to a local denial of service. (CVE-2008-5300, Important)

* the exit_notify() function in the Linux kernel did not properly reset the exit signal if a process executed a set user ID (setuid) application before exiting. This could allow a local, unprivileged user to elevate their privileges. (CVE-2009-1337, Important)

* a flaw was found in the Intel PRO/1000 network driver in the Linux kernel. Frames with sizes near the MTU of an interface may be split across multiple hardware receive descriptors. Receipt of such a frame could leak through a validation check, leading to a corruption of the length check. A remote attacker could use this flaw to send a specially crafted packet that would cause a denial of service or code execution. (CVE-2009-1385, Important)

* the ADDR_COMPAT_LAYOUT and MMAP_PAGE_ZERO flags were not cleared when a setuid or setgid program was executed. A local, unprivileged user could use this flaw to bypass the mmap_min_addr protection mechanism and perform a NULL pointer dereference attack, or bypass the Address Space Layout Randomization (ASLR) security feature.
(CVE-2009-1895, Important)

* it was discovered that, when executing a new process, the clear_child_tid pointer in the Linux kernel is not cleared. If this pointer points to a writable portion of the memory of the new program, the kernel could corrupt four bytes of memory, possibly leading to a local denial of service or privilege escalation. (CVE-2009-2848, Important)

* missing initialization flaws were found in getname() implementations in the IrDA sockets, AppleTalk DDP protocol, NET/ROM protocol, and ROSE protocol implementations in the Linux kernel. Certain data structures in these getname() implementations were not initialized properly before being copied to user-space. These flaws could lead to an information leak. (CVE-2009-3002, Important)

* a NULL pointer dereference flaw was found in each of the following functions in the Linux kernel: pipe_read_open(), pipe_write_open(), and pipe_rdwr_open(). When the mutex lock is not held, the i_pipe pointer could be released by other processes before it is used to update the pipe's reader and writer counters. This could lead to a local denial of service or privilege escalation. (CVE-2009-3547, Important)

Bug fixes :

* this update adds the mmap_min_addr tunable and restriction checks to help prevent unprivileged users from creating new memory mappings below the minimum address. This can help prevent the exploitation of NULL pointer dereference bugs. Note that mmap_min_addr is set to zero (disabled) by default for backwards compatibility. (BZ#512642)

* a bridge reference count problem in IPv6 has been fixed. (BZ#457010)

* enforce null-termination of user-supplied arguments to setsockopt().
(BZ#505514)

* the gcc flag '-fno-delete-null-pointer-checks' was added to the kernel build options. This prevents gcc from optimizing out NULL pointer checks after the first use of a pointer. NULL pointer bugs are often exploited by attackers. Keeping these checks is a safety measure. (BZ#511185)

* a check has been added to the IPv4 code to make sure that rt is not NULL, to help prevent future bugs in functions that call ip_append_data() from being exploitable. (BZ#520300)

Users should upgrade to these updated packages, which contain backported patches to correct these issues. The system must be rebooted for this update to take effect.

b. ESXi userworld update for ntp

   The Network Time Protocol (NTP) is used to synchronize the time of    a computer client or server to another server or reference time    source.

   A vulnerability in ntpd could allow a remote attacker to cause a    denial of service (CPU and bandwidth consumption) by using    MODE_PRIVATE to send a spoofed (1) request or (2) response packet    that triggers a continuous exchange of MODE_PRIVATE error responses    between two NTP daemons.

   The Common Vulnerabilities and Exposures Project (cve.mitre.org)    has assigned the name CVE-2009-3563 to this issue.

c. Service Console package openssl updated to 0.9.8e-12.el5_4.1

   OpenSSL is a toolkit implementing SSL v2/v3 and TLS protocols with    full-strength cryptography world-wide.

   A memory leak in the zlib could allow a remote attacker to cause a    denial of service (memory consumption) via vectors that trigger    incorrect calls to the CRYPTO_cleanup_all_ex_data function.

   The Common Vulnerabilities and Exposures Project (cve.mitre.org)    has assigned the name CVE-2009-4355 to this issue.

   A vulnerability was discovered which may allow remote attackers to    spoof certificates by using MD2 design flaws to generate a hash    collision in less than brute-force time. NOTE: the scope of this    issue is currently limited because the amount of computation    required is still large.

   The Common Vulnerabilities and Exposures Project (cve.mitre.org)    has assigned the name CVE-2009-2409 to this issue.

   This update also includes security fixes that were first addressed    in version openssl-0.9.8e-12.el5.i386.rpm.

   The Common Vulnerabilities and Exposures Project (cve.mitre.org)    has assigned the names CVE-2009-0590, CVE-2009-1377, CVE-2009-1378,    CVE-2009-1379, CVE-2009-1386 and CVE-2009-1387 to these issues.

d. Service Console update for krb5 to 1.6.1-36.el5_4.1 and pam_krb5 to    2.2.14-15.

   Kerberos is a network authentication protocol. It is designed to    provide strong authentication for client/server applications by    using secret-key cryptography.

   Multiple integer underflows in the AES and RC4 functionality in the    crypto library could allow remote attackers to cause a denial of    service (daemon crash) or possibly execute arbitrary code by    providing ciphertext with a length that is too short to be valid.

   The Common Vulnerabilities and Exposures Project (cve.mitre.org)    has assigned the name CVE-2009-4212 to this issue.

   The service console package for pam_krb5 is updated to version    pam_krb5-2.2.14-15. This update fixes a flaw found in pam_krb5. In    some non-default configurations (specifically, where pam_krb5 would    be the first module to prompt for a password), a remote attacker    could use this flaw to recognize valid usernames, which would aid a    dictionary-based password guess attack.

   The Common Vulnerabilities and Exposures Project (cve.mitre.org)    has assigned the name CVE-2009-1384 to this issue.

e. Service Console package bind updated to 9.3.6-4.P1.el5_4.2

   BIND (Berkeley Internet Name Daemon) is by far the most widely used    Domain Name System (DNS) software on the Internet.

   A vulnerability was discovered which could allow remote attacker to    add the Authenticated Data (AD) flag to a forged NXDOMAIN response    for an existing domain.

   The Common Vulnerabilities and Exposures Project (cve.mitre.org)    has assigned the name CVE-2010-0097 to this issue.

   A vulnerability was discovered which could allow remote attackers    to conduct DNS cache poisoning attacks by receiving a recursive    client query and sending a response that contains CNAME or DNAME    records, which do not have the intended validation before caching.

   The Common Vulnerabilities and Exposures Project (cve.mitre.org)    has assigned the name CVE-2010-0290 to this issue.

   A vulnerability was found in the way that bind handles out-of-    bailiwick data accompanying a secure response without re-fetching    from the original source, which could allow remote attackers to    have an unspecified impact via a crafted response.

   The Common Vulnerabilities and Exposures Project (cve.mitre.org)    has assigned the name CVE-2010-0382 to this issue.

   NOTE: ESX does not use the BIND name service daemon by default.

f. Service Console package gcc updated to 3.2.3-60

   The GNU Compiler Collection includes front ends for C, C++,    Objective-C, Fortran, Java, and Ada, as well as libraries for these    languages

   GNU Libtool's ltdl.c attempts to open .la library files in the    current working directory.  This could allow a local user to gain    privileges via a Trojan horse file.  The GNU C Compiler collection    (gcc) provided in ESX contains a statically linked version of the    vulnerable code, and is being replaced.

   The Common Vulnerabilities and Exposures Project (cve.mitre.org)    has assigned the name CVE-2009-3736 to this issue.

g. Service Console package gzip update to 1.3.3-15.rhel3

   gzip is a software application used for file compression

   An integer underflow in gzip's unlzw function on 64-bit platforms    may allow a remote attacker to trigger an array index error    leading to a denial of service (application crash) or possibly    execute arbitrary code via a crafted LZW compressed file.

   The Common Vulnerabilities and Exposures Project (cve.mitre.org)    has assigned the name CVE-2010-0001 to this issue.

h. Service Console package sudo updated to 1.6.9p17-6.el5_4

   Sudo (su 'do') allows a system administrator to delegate authority    to give certain users (or groups of users) the ability to run some    (or all) commands as root or another user while providing an audit    trail of the commands and their arguments.

   When a pseudo-command is enabled, sudo permits a match between the    name of the pseudo-command and the name of an executable file in an    arbitrary directory, which allows local users to gain privileges    via a crafted executable file.

   The Common Vulnerabilities and Exposures Project (cve.mitre.org)    has assigned the name CVE-2010-0426 to this issue.

   When the runas_default option is used, sudo does not properly set    group memberships, which allows local users to gain privileges via    a sudo command.

   The Common Vulnerabilities and Exposures Project (cve.mitre.org)    has assigned the name CVE-2010-0427 to this issue.

Updated kernel packages that fix multiple security issues and several bugs are now available for Red Hat Enterprise Linux 5.

This update has been rated as having important security impact by the Red Hat Security Response Team.

The kernel packages contain the Linux kernel, the core of any Linux operating system.

Security fixes :

* a system with SELinux enforced was more permissive in allowing local users in the unconfined_t domain to map low memory areas even if the mmap_min_addr restriction was enabled. This could aid in the local exploitation of NULL pointer dereference bugs. (CVE-2009-2695, Important)

* a NULL pointer dereference flaw was found in the eCryptfs implementation in the Linux kernel. A local attacker could use this flaw to cause a local denial of service or escalate their privileges.
(CVE-2009-2908, Important)

* a flaw was found in the NFSv4 implementation. The kernel would do an unnecessary permission check after creating a file. This check would usually fail and leave the file with the permission bits set to random values. Note: This is a server-side only issue. (CVE-2009-3286, Important)

* a NULL pointer dereference flaw was found in each of the following functions in the Linux kernel: pipe_read_open(), pipe_write_open(), and pipe_rdwr_open(). When the mutex lock is not held, the i_pipe pointer could be released by other processes before it is used to update the pipe's reader and writer counters. This could lead to a local denial of service or privilege escalation. (CVE-2009-3547, Important)

* a flaw was found in the Realtek r8169 Ethernet driver in the Linux kernel. pci_unmap_single() presented a memory leak that could lead to IOMMU space exhaustion and a system crash. An attacker on the local network could abuse this flaw by using jumbo frames for large amounts of network traffic. (CVE-2009-3613, Important)

* missing initialization flaws were found in the Linux kernel. Padding data in several core network structures was not initialized properly before being sent to user-space. These flaws could lead to information leaks. (CVE-2009-3228, Moderate)

Bug fixes :

* with network bonding in the 'balance-tlb' or 'balance-alb' mode, the primary setting for the primary slave device was lost when said device was brought down. Bringing the slave back up did not restore the primary setting. (BZ#517971)

* some faulty serial device hardware caused systems running the kernel-xen kernel to take a very long time to boot. (BZ#524153)

* a caching bug in nfs_readdir() may have caused NFS clients to see duplicate files or not see all files in a directory. (BZ#526960)

* the RHSA-2009:1243 update removed the mpt_msi_enable option, preventing certain scripts from running. This update adds the option back. (BZ#526963)

* an iptables rule with the recent module and a hit count value greater than the ip_pkt_list_tot parameter (the default is 20), did not have any effect over packets, as the hit count could not be reached. (BZ#527434)

* a check has been added to the IPv4 code to make sure that rt is not NULL, to help prevent future bugs in functions that call ip_append_data() from being exploitable. (BZ#527436)

* a kernel panic occurred in certain conditions after reconfiguring a tape drive's block size. (BZ#528133)

* when using the Linux Virtual Server (LVS) in a master and backup configuration, and propagating active connections on the master to the backup, the connection timeout value on the backup was hard-coded to 180 seconds, meaning connection information on the backup was soon lost. This could prevent the successful failover of connections. The timeout value can now be set via 'ipvsadm --set'. (BZ#528645)

* a bug in nfs4_do_open_expired() could have caused the reclaimer thread on an NFSv4 client to enter an infinite loop. (BZ#529162)

* MSI interrupts may not have been delivered for r8169 based network cards that have MSI interrupts enabled. This bug only affected certain systems. (BZ#529366)
