Debian: New python2.4 packages fix several vulnerabilities
by Patrick Lenz, in Security - Sun, Apr 20th 2008 15:31 UTC
Several vulnerabilities have been discovered in the interpreter for the Python language. Piotr Engelking discovered that the strxfrm() function of the locale module miscalculates the length of an internal buffer, which may result in a minor information disclosure. It was discovered that several integer overflows in the imageop module may lead to the execution of arbitrary code, if a user is tricked into processing malformed images. Justin Ferguson discovered that a buffer overflow in the zlib module may lead to the execution of arbitrary code. Justin Ferguson discovered that insufficient input validation in PyString_FromStringAndSize() may lead to the execution of arbitrary code. Fixed packages are available from security.debian.org.

Package : python2.4
Vulnerability : several
Problem type : local(remote)
Debian-specific: no
CVE Id(s) : CVE-2007-2052 CVE-2007-4965 CVE-2008-1679 CVE-2008-1721 CVE-2008-1887
Several vulnerabilities have been discovered in the interpreter for the
Python language. The Common Vulnerabilities and Exposures project identifies
the following problems:
CVE-2007-2052
Piotr Engelking discovered that the strxfrm() function of the locale
module miscalculates the length of an internal buffer, which may
result in a minor information disclosure.
CVE-2007-4965
It was discovered that several integer overflows in the imageop
module may lead to the execution of arbitrary code, if a user is
tricked into processing malformed images. This issue is also
tracked as CVE-2008-1679 due to an initially incomplete patch.
CVE-2008-1721
Justin Ferguson discovered that a buffer overflow in the zlib
module may lead to the execution of arbitrary code.
CVE-2008-1887
Justin Ferguson discovered that insufficient input validation in
PyString_FromStringAndSize() may lead to the execution of arbitrary
code.
For the stable distribution (etch), these problems have been fixed in
version 2.4.4-3+etch1.
For the unstable distribution (sid), these problems have been fixed in
version 2.4.5-2.
We recommend that you upgrade your python2.4 packages.
Upgrade instructions
- --------------------
