Synopsis ========
Multiple vulnerabilities in Python may allow for the execution of arbitrary code.
Background ==========
Python is an interpreted, interactive, object-oriented programming language.
Affected packages =================
------------------------------------------------------------------- Package / Vulnerable / Unaffected ------------------------------------------------------------------- 1 dev-lang/python < 2.5.2-r6 *>= 2.4.4-r14 >= 2.5.2-r6
Description ===========
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).
Impact ======
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.
Workaround ==========
There is no known workaround at this time.
Resolution ==========
All 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.
