GLSA-200807-01 : Python: Multiple integer overflows
high Nessus Plugin ID 33421
Synopsis
The remote Gentoo host is missing one or more security-related patches.Description
The remote host is affected by the vulnerability described in GLSA-200807-01 (Python: Multiple integer overflows)Multiple vulnerabilities were discovered in Python:
David Remahl reported multiple integer overflows in the file imageop.c, leading to a heap-based buffer overflow (CVE-2008-1679). This issue is due to an incomplete fix for CVE-2007-4965.
Justin Ferguson discovered that an integer signedness error in the zlib extension module might trigger insufficient memory allocation and a buffer overflow via a negative signed integer (CVE-2008-1721).
Justin Ferguson discovered that insufficient input validation in the PyString_FromStringAndSize() function might lead to a buffer overflow (CVE-2008-1887).
Impact :
A remote attacker could exploit these vulnerabilities to cause a Denial of Service or possibly the remote execution of arbitrary code with the privileges of the user running Python.
Workaround :
There is no known workaround at this time.
Solution
The imageop module is no longer built in the unaffected versions.All Python 2.3 users should upgrade to the latest version:
# emerge --sync # emerge --ask --oneshot --verbose '>=dev-lang/python-2.3.6-r6' All Python 2.4 users should upgrade to the latest version:
# emerge --sync # emerge --ask --oneshot --verbose '>=dev-lang/python-2.4.4-r13'
