====================================================================
1. Summary:

Updated python packages that fix multiple security issues are now available
for Red Hat Enterprise Linux 3.

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

2. Relevant releases/architectures:

Red Hat Enterprise Linux AS version 3 - i386, ia64, ppc, s390, s390x, x86_64
Red Hat Desktop version 3 - i386, x86_64
Red Hat Enterprise Linux ES version 3 - i386, ia64, x86_64
Red Hat Enterprise Linux WS version 3 - i386, ia64, x86_64

3. Description:

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 crash or, potentially, execute arbitrary
code with the Python interpreter's privileges. (CVE-2008-1679,
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)

Red Hat would like to thank David Remahl of the Apple Product Security team
for responsibly reporting the CVE-2008-1679 and CVE-2008-2315 issues.

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

4. Solution:

Before applying this update, make sure that all previously-released
errata relevant to your system have been applied.

This update is available via Red Hat Network.  Details on how to use
the Red Hat Network to apply this update are available at
