The remote Redhat Enterprise Linux 5 host has packages installed that are affected by multiple vulnerabilities as referenced in the RHSA-2009:1176 advisory.

    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.

This update of python fixes several security vulnerabilities.
(CVE-2008-1679,CVE-2008-1887, CVE-2008-3143, CVE-2008-3142, CVE-2008-3144, CVE-2008-2315, CVE-2008-2316)

Multiple integer overflows in the imageop module in Python prior to 2.5.3 allowed context-dependent attackers to cause a denial of service (crash) or possibly execute arbitrary code via crafted images that trigger heap-based buffer overflows (CVE-2008-1679). This was due to an incomplete fix for CVE-2007-4965.

David Remahl of Apple Product Security reported several integer overflows in a number of core modules (CVE-2008-2315). He also reported an integer overflow in the hashlib module on Python 2.5 that lead to unreliable cryptographic digest results (CVE-2008-2316).

Justin Ferguson reported multiple buffer overflows in unicode string processing that affected 32bit systems (CVE-2008-3142).

Multiple integer overflows were reported by the Google Security Team that had been fixed in Python 2.5.2 (CVE-2008-3143).

Justin Ferguson reported a number of integer overflows and underflows in the PyOS_vsnprintf() function, as well as an off-by-one error when passing zero-length strings, that led to memory corruption (CVE-2008-3144).

The updated packages have been patched to correct these issues. As well, Python packages on Mandriva Linux 2007.1 and 2008.0 have been updated to version 2.5.2. Due to slight packaging changes on Mandriva Linux 2007.1, a new package is available (tkinter-apps) that contains binary files (such as /usr/bin/idle) that were previously in the tkinter package.

The remote host is running a version of Mac OS X 10.5 or 10.4 that does not have Security Update 2009-001 applied.

Several vulnerabilities have been discovered in the interpreter for the Python language. The Common Vulnerabilities and Exposures project identifies the following problems :

  - CVE-2008-2315     David Remahl discovered several integer overflows in the     stringobject, unicodeobject, bufferobject, longobject,     tupleobject, stropmodule, gcmodule, and mmapmodule     modules.

  - CVE-2008-3142     Justin Ferguson discovered that incorrect memory     allocation in the unicode_resize() function can lead to     buffer overflows.

  - CVE-2008-3143     Several integer overflows were discovered in various     Python core modules.

  - CVE-2008-3144     Several integer overflows were discovered in the     PyOS_vsnprintf() function.

Secunia reports :

Some vulnerabilities have been reported in Python, where some have unknown impact and others can potentially be exploited by malicious people to cause a DoS (Denial of Service) or to compromise a vulnerable system.

Various integer overflow errors exist in core modules e.g.
stringobject, unicodeobject, bufferobject, longobject, tupleobject, stropmodule, gcmodule, mmapmodule.

An integer overflow in the hashlib module can lead to an unreliable cryptographic digest results.

Integer overflow errors in the processing of unicode strings can be exploited to cause buffer overflows on 32-bit systems.

An integer overflow exists in the PyOS_vsnprintf() function on architectures that do not have a 'vsnprintf()' function.

An integer underflow error in the PyOS_vsnprintf() function when passing zero-length strings can lead to memory corruption.

This update of python fixes several security vulnerabilities.
(CVE-2008-1679 / CVE-2008-1887 / CVE-2008-3143 / CVE-2008-3142 / CVE-2008-3144 / CVE-2008-2315 / CVE-2008-2316) Note: for SLE10 a non-security bug in mmap was fixed too.

New python packages are available for Slackware 10.1, 10.2, 11.0, 12.0, 12.1, and -current to fix security issues.

It was discovered that there were new integer overflows in the imageop module. If an attacker were able to trick a Python application into processing a specially crafted image, they could execute arbitrary code with user privileges. (CVE-2008-1679)

Justin Ferguson discovered that the zlib module did not correctly handle certain archives. If an attacker were able to trick a Python application into processing a specially crafted archive file, they could execute arbitrary code with user privileges. (CVE-2008-1721)

Justin Ferguson discovered that certain string manipulations in Python could be made to overflow. If an attacker were able to pass a specially crafted string through the PyString_FromStringAndSize function, they could execute arbitrary code with user privileges.
(CVE-2008-1887)

Multiple integer overflows were discovered in Python's core and modules including hashlib, binascii, pickle, md5, stringobject, unicodeobject, bufferobject, longobject, tupleobject, stropmodule, gcmodule, and mmapmodule. If an attacker were able to exploit these flaws they could execute arbitrary code with user privileges or cause Python applications to crash, leading to a denial of service.
(CVE-2008-2315, CVE-2008-2316, CVE-2008-3142, CVE-2008-3143, CVE-2008-3144).

The remote host is affected by the vulnerability described in GLSA-200807-16 (Python: Multiple vulnerabilities)

    Multiple vulnerabilities were discovered in Python:
    David Remahl of Apple Product Security reported several integer     overflows in core modules such as stringobject, unicodeobject,     bufferobject, longobject, tupleobject, stropmodule, gcmodule,     mmapmodule (CVE-2008-2315).
    David Remahl of Apple Product Security also reported an integer     overflow in the hashlib module, leading to unreliable cryptographic     digest results (CVE-2008-2316).
    Justin Ferguson reported multiple buffer overflows in unicode string     processing that only affect 32bit systems (CVE-2008-3142).
    The Google Security Team reported multiple integer overflows     (CVE-2008-3143).
    Justin Ferguson reported multiple integer underflows and overflows in     the PyOS_vsnprintf() function, and an off-by-one error when passing     zero-length strings, leading to memory corruption (CVE-2008-3144).
  Impact :

    A remote attacker could exploit these vulnerabilities in Python     applications or daemons that pass user-controlled input to vulnerable     functions. Exploitation might lead to the execution of arbitrary code     or a Denial of Service. Vulnerabilities within the hashlib might lead     to weakened cryptographic protection of data integrity or authenticity.
  Workaround :

    There is no known workaround at this time.
