a. ESX third-party update for Service Console kernel      The ESX Service Console Operating System (COS) kernel is updated to    kernel-2.6.18-274.3.1.el5 to fix multiple security issues in the    COS kernel.
     The Common Vulnerabilities and Exposures project (cve.mitre.org) has    assigned the names CVE-2011-0726, CVE-2011-1078, CVE-2011-1079,    CVE-2011-1080, CVE-2011-1093, CVE-2011-1163, CVE-2011-1166,    CVE-2011-1170, CVE-2011-1171, CVE-2011-1172, CVE-2011-1494,    CVE-2011-1495, CVE-2011-1577, CVE-2011-1763, CVE-2010-4649,    CVE-2011-0695, CVE-2011-0711, CVE-2011-1044, CVE-2011-1182,    CVE-2011-1573, CVE-2011-1576, CVE-2011-1593, CVE-2011-1745,    CVE-2011-1746, CVE-2011-1776, CVE-2011-1936, CVE-2011-2022,    CVE-2011-2213, CVE-2011-2492, CVE-2011-1780, CVE-2011-2525,    CVE-2011-2689, CVE-2011-2482, CVE-2011-2491, CVE-2011-2495,    CVE-2011-2517, CVE-2011-2519, CVE-2011-2901 to these issues.
  b. ESX third-party update for Service Console cURL RPM      The ESX Service Console (COS) curl RPM is updated to cURL-7.15.5.9    resolving a security issues.
     The Common Vulnerabilities and Exposures project (cve.mitre.org) has    assigned the name CVE-2011-2192 to this issue.
  c. ESX third-party update for Service Console nspr and nss RPMs      The ESX Service Console (COS) nspr and nss RPMs are updated to    nspr-4.8.8-1.el5_7 and nss-3.12.10-4.el5_7 respectively resolving    a security issues.
     A Certificate Authority (CA) issued fraudulent SSL certificates and    Netscape Portable Runtime (NSPR) and Network Security Services (NSS)    contain the built-in tokens of this fraudulent Certificate    Authority. This update renders all SSL certificates signed by the    fraudulent CA as untrusted for all uses.
  d. ESX third-party update for Service Console rpm RPMs      The ESX Service Console Operating System (COS) rpm packages are    updated to popt-1.10.2.3-22.el5_7.2, rpm-4.4.2.3-22.el5_7.2,    rpm-libs-4.4.2.3-22.el5_7.2 and rpm-python-4.4.2.3-22.el5_7.2    which fixes multiple security issues.
     The Common Vulnerabilities and Exposures project (cve.mitre.org) has    assigned the names CVE-2010-2059 and CVE-2011-3378 to these    issues.
  e. ESX third-party update for Service Console samba RPMs      The ESX Service Console Operating System (COS) samba packages are    updated to samba-client-3.0.33-3.29.el5_7.4,    samba-common-3.0.33-3.29.el5_7.4 and    libsmbclient-3.0.33-3.29.el5_7.4 which fixes multiple security    issues in the Samba client.
     The Common Vulnerabilities and Exposures project (cve.mitre.org) has    assigned the names CVE-2010-0547, CVE-2010-0787, CVE-2011-1678,    CVE-2011-2522 and CVE-2011-2694 to these issues.
     Note that ESX does not include the Samba Web Administration Tool    (SWAT) and therefore ESX COS is not affected by CVE-2011-2522 and    CVE-2011-2694.
  f. ESX third-party update for Service Console python package      The ESX Service Console (COS) python package is updated to    2.4.3-44 which fixes multiple security issues.

  g. ESXi update to third-party component python      The python third-party library is updated to python 2.5.6 which    fixes multiple security issues.
     The Common Vulnerabilities and Exposures project (cve.mitre.org) has    assigned the names CVE-2009-3560, CVE-2009-3720, CVE-2010-1634,    CVE-2010-2089, and CVE-2011-1521 to these issues.

It was found that many applications embedding the Python interpreter did not specify a valid full path to the script or application when calling the PySys_SetArgv API function, which could result in the addition of the current working directory to the module search path (sys.path). A local attacker able to trick a victim into running such an application in an attacker-controlled directory could use this flaw to execute code with the victim's privileges. This update adds the PySys_SetArgvEx API. Developers can modify their applications to use this new API, which sets sys.argv without modifying sys.path.
(CVE-2008-5983)

Multiple flaws were found in the Python rgbimg module. If an application written in Python was using the rgbimg module and loaded a specially crafted SGI image file, it could cause the application to crash or, possibly, execute arbitrary code with the privileges of the user running the application. (CVE-2009-4134, CVE-2010-1449, CVE-2010-1450)

Multiple flaws were found in the Python audioop module. Supplying certain inputs could cause the audioop module to crash or, possibly, execute arbitrary code. (CVE-2010-1634, CVE-2010-2089)

This update also fixes the following bugs :

  - When starting a child process from the subprocess module     in Python 2.4, the parent process could leak file     descriptors if an error occurred. This update resolves     the issue. (BZ#609017)

  - Prior to Python 2.7, programs that used 'ulimit -n' to     enable communication with large numbers of subprocesses     could still monitor only 1024 file descriptors at a     time, which caused an exception :

    ValueError: filedescriptor out of range in select()

This was due to the subprocess module using the 'select' system call.
The module now uses the 'poll' system call, removing this limitation.
(BZ#609020)

  - Prior to Python 2.5, the tarfile module failed to unpack     tar files if the path was longer than 100 characters.
    This update backports the tarfile module from Python 2.5     and the issue no longer occurs. (BZ#263401)

  - The email module incorrectly implemented the logic for     obtaining attachment file names: the get_filename()     fallback for using the deprecated 'name' parameter of     the 'Content-Type' header erroneously used the     'Content-Disposition' header. This update backports a     fix from Python 2.6, which resolves this issue.
    (BZ#644147)

  - Prior to version 2.5, Python's optimized memory     allocator never released memory back to the system. The     memory usage of a long-running Python process would     resemble a 'high-water mark'. This update backports a     fix from Python 2.5a1, which frees unused arenas, and     adds a non-standard sys._debugmallocstats() function,     which prints diagnostic information to stderr. Finally,     when running under Valgrind, the optimized allocator is     deactivated, to allow more convenient debugging of     Python memory usage issues. (BZ#569093)

  - The urllib and urllib2 modules ignored the no_proxy     variable, which could lead to programs such as 'yum'     erroneously accessing a proxy server for URLs covered by     a 'no_proxy' exclusion. This update backports fixes of     urllib and urllib2, which respect the 'no_proxy'     variable, which fixes these issues. (BZ#549372)

As well, this update adds the following enhancements :

  - This update introduces a new python-libs package,     subsuming the majority of the content of the core python     package. This makes both 32-bit and 64-bit Python     libraries available on PowerPC systems. (BZ#625372)

  - The python-libs.i386 package is now available for 64-bit     Itanium with the 32-bit Itanium compatibility mode.
    (BZ#644761)

- Fri Jun 4 2010 David Malcolm <dmalcolm at redhat.com> -     2.6.4-27

    - ensure that the compiler is invoked with '-fwrapv'       (rhbz#594819)

    - CVE-2010-1634: fix various integer overflow checks in       the audioop module (patch 113)

  - CVE-2010-2089: further checks within the audioop module     (patch 114)

    - CVE-2008-5983: the new PySys_SetArgvEx entry point       from r81399 (patch 115)

    - Mon Apr 26 2010 Dennis Gilmore <dennis at ausil.us> -       2.6.4-26

    - disable --with-valgrind on sparc arches

- Backport from F14: - Fix for lone surrogates, utf8 and     certain encode error handlers. - Fix an incompatibility     between pyexpat and the system expat-2.0.1 that led to a     segfault running test_pyexpat.py (patch 110; upstream     issue 9054; rhbz#610312)

- a race condition in the accept() implementation of     smtpd.py could lead to a denial of service     (CVE-2010-3493).

  - integer overflows and insufficient size checks could     crash the audioop module (CVE-2010-2089, CVE-2010-1634).
