GLSA-200807-01 : Python: Multiple integer overflows
High Nessus Plugin ID 33421
SynopsisThe remote Gentoo host is missing one or more security-related patches.
DescriptionThe 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).
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.
There is no known workaround at this time.
SolutionThe 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'
