Background ========== Python is an interpreted, interactive, object-oriented, cross-platform programming language. Affected packages ================= ------------------------------------------------------------------- Package / Vulnerable / Unaffected ------------------------------------------------------------------- 1 dev-lang/python < 2.4.3-r4 >= 2.4.3-r4 *>= 2.3.5-r3 Description =========== Benjamin C. Wiley Sittler discovered a buffer overflow in Python's "repr()" function when handling UTF-32/UCS-4 encoded strings. Impact ====== If a Python application processes attacker-supplied data with the "repr()" function, this could potentially lead to the execution of arbitrary code with the privileges of the affected application or a Denial of Service. Workaround ========== There is no known workaround at this time. Resolution ========== All Python users should update to the latest version: # emerge --sync # emerge --ask --oneshot --verbose ">=dev-lang/2.4.3-r4" References ========== [ 1 ] CVE-2006-4980 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2006-4980 Availability ============ This GLSA and any updates to it are available for viewing at the Gentoo Security Website: http://security.gentoo.org/glsa/glsa-200610-07.xml Concerns? ========= Security is a primary focus of Gentoo Linux and ensuring the confidentiality and security of our users machines is of utmost importance to us. Any security concerns should be addressed to security () gentoo org or alternatively, you may file a bug at http://bugs.gentoo.org.
