DSA-1551-1 python2.4 -- several vulnerabilities
Date Reported:
19 Apr 2008
Affected Packages:
python2.4
Vulnerable:
Yes
Security database references:
In Mitre's CVE dictionary: CVE-2007-2052, CVE-2007-4965, CVE-2008-1679,
CVE-2008-1721, CVE-2008-1887.
More information:
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.
Fixed in:
Debian GNU/Linux 4.0 (stable)
