GLSA-200807-16 : Python: Multiple vulnerabilities
High Nessus Plugin ID 33782
SynopsisThe remote Gentoo host is missing one or more security-related patches.
DescriptionThe remote host is affected by the vulnerability described in GLSA-200807-16 (Python: Multiple vulnerabilities)
Multiple vulnerabilities were discovered in Python:
David Remahl of Apple Product Security reported several integer overflows in core modules such as stringobject, unicodeobject, bufferobject, longobject, tupleobject, stropmodule, gcmodule, mmapmodule (CVE-2008-2315).
David Remahl of Apple Product Security also reported an integer overflow in the hashlib module, leading to unreliable cryptographic digest results (CVE-2008-2316).
Justin Ferguson reported multiple buffer overflows in unicode string processing that only affect 32bit systems (CVE-2008-3142).
The Google Security Team reported multiple integer overflows (CVE-2008-3143).
Justin Ferguson reported multiple integer underflows and overflows in the PyOS_vsnprintf() function, and an off-by-one error when passing zero-length strings, leading to memory corruption (CVE-2008-3144).
A remote attacker could exploit these vulnerabilities in Python applications or daemons that pass user-controlled input to vulnerable functions. Exploitation might lead to the execution of arbitrary code or a Denial of Service. Vulnerabilities within the hashlib might lead to weakened cryptographic protection of data integrity or authenticity.
There is no known workaround at this time.
SolutionAll Python 2.4 users should upgrade to the latest version:
# emerge --sync # emerge --ask --oneshot --verbose '>=dev-lang/python-2.4.4-r14' All Python 2.5 users should upgrade to the latest version:
# emerge --sync # emerge --ask --oneshot --verbose '>=dev-lang/python-2.5.2-r6' Please note that Python 2.3 is masked since June 24, and we will not be releasing updates to it. It will be removed from the tree in the near future.
