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

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

Python is an interpreted, interactive, object-oriented programming language.

When the assert() system call was disabled, an input sanitization flaw was revealed in the Python string object implementation that led to a buffer overflow. The missing check for negative size values meant the Python memory allocator could allocate less memory than expected. This could result in arbitrary code execution with the Python interpreter's privileges. (CVE-2008-1887)

Multiple buffer and integer overflow flaws were found in the Python Unicode string processing and in the Python Unicode and string object implementations. An attacker could use these flaws to cause a denial of service (Python application crash). (CVE-2008-3142, CVE-2008-5031)

Multiple integer overflow flaws were found in the Python imageop module. If a Python application used the imageop module to process untrusted images, it could cause the application to disclose sensitive information, crash or, potentially, execute arbitrary code with the Python interpreter's privileges. (CVE-2007-4965, CVE-2008-4864)

Multiple integer underflow and overflow flaws were found in the Python snprintf() wrapper implementation. An attacker could use these flaws to cause a denial of service (memory corruption). (CVE-2008-3144)

Multiple integer overflow flaws were found in various Python modules.
An attacker could use these flaws to cause a denial of service (Python application crash). (CVE-2008-2315, CVE-2008-3143)

An integer signedness error, leading to a buffer overflow, was found in the Python zlib extension module. If a Python application requested the negative byte count be flushed for a decompression stream, it could cause the application to crash or, potentially, execute arbitrary code with the Python interpreter's privileges.
(CVE-2008-1721)

A flaw was discovered in the strxfrm() function of the Python locale module. Strings generated by this function were not properly NULL-terminated, which could possibly cause disclosure of data stored in the memory of a Python application using this function.
(CVE-2007-2052)

Red Hat would like to thank David Remahl of the Apple Product Security team for responsibly reporting the CVE-2008-2315 issue.

All Python users should upgrade to these updated packages, which contain backported patches to correct these issues.

An integer overflow flaw was discovered in the way Python's pcre module handled certain regular expressions. If a Python application used the pcre module to compile and execute untrusted regular expressions, it may be possible to cause the application to crash, or allow arbitrary code execution with the privileges of the Python interpreter. (CVE-2006-7228)

A flaw was discovered in the strxfrm() function of Python's locale module. Strings generated by this function were not properly NULL-terminated. This may possibly cause disclosure of data stored in the memory of a Python application using this function.
(CVE-2007-2052)

Multiple integer overflow flaws were discovered in Python's imageop module. If an application written in Python used the imageop module to process untrusted images, it could cause the application to crash, enter an infinite loop, or possibly execute arbitrary code with the privileges of the Python interpreter. (CVE-2007-4965)

The remote NewStart CGSL host, running version MAIN 5.04, has python packages installed that are affected by multiple vulnerabilities:

  - Multiple integer overflows in the imageop module in     Python 2.5.1 and earlier allow context-dependent     attackers to cause a denial of service (application     crash) and possibly obtain sensitive information (memory     contents) via crafted arguments to (1) the tovideo     method, and unspecified other vectors related to (2)     imageop.c, (3) rbgimgmodule.c, and other files, which     trigger heap-based buffer overflows. (CVE-2007-4965)

  - Integer overflow in _hashopenssl.c in the hashlib module     in Python 2.5.2 and earlier might allow context-     dependent attackers to defeat cryptographic digests,     related to partial hashlib hashing of data exceeding     4GB. (CVE-2008-2316)

  - Untrusted search path vulnerability in the PySys_SetArgv     API function in Python 2.6 and earlier, and possibly     later versions, prepends an empty string to sys.path     when the argv[0] argument does not contain a path     separator, which might allow local users to execute     arbitrary code via a Trojan horse Python file in the     current working directory. (CVE-2008-5983)

  - Multiple integer overflows in audioop.c in the audioop     module in Python 2.6, 2.7, 3.1, and 3.2 allow context-     dependent attackers to cause a denial of service     (application crash) via a large fragment, as     demonstrated by a call to audioop.lin2lin with a long     string in the first argument, leading to a buffer     overflow. NOTE: this vulnerability exists because of an     incorrect fix for CVE-2008-3143.5. (CVE-2010-1634)

  - The audioop module in Python 2.7 and 3.2 does not verify     the relationships between size arguments and byte string     lengths, which allows context-dependent attackers to     cause a denial of service (memory corruption and     application crash) via crafted arguments, as     demonstrated by a call to audioop.reverse with a one-     byte string, a different vulnerability than     CVE-2010-1634. (CVE-2010-2089)

  - The ssl.match_hostname function in the SSL module in     Python 2.6 through 3.4 does not properly handle a '\0'     character in a domain name in the Subject Alternative     Name field of an X.509 certificate, which allows man-in-     the-middle attackers to spoof arbitrary SSL servers via     a crafted certificate issued by a legitimate     Certification Authority, a related issue to     CVE-2009-2408. (CVE-2013-4238)

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.
