Background ========== Python is an interpreted, interactive, object-oriented, cross-platform programming language. Affected packages ================= ------------------------------------------------------------------- Package / Vulnerable / Unaffected ------------------------------------------------------------------- 1 dev-lang/python < 2.2.2 >= 2.2.2 < 2.2 Description =========== If IPV6 is disabled in Python 2.2, getaddrinfo() is not able to handle IPV6 DNS requests properly and a buffer overflow occurs. Impact ====== An attacker can execute arbitrary code as the user running python. Workaround ========== Users with IPV6 enabled are not affected by this vulnerability. Resolution ========== All Python 2.2 users should upgrade to the latest version: # emerge sync # emerge -pv ">=dev-lang/python-2.2.2" # emerge ">=dev-lang/python-2.2.2" References ========== [ 1 ] CVE-2004-0150 http://www.cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2004-0150 [ 2 ] OSVDB:4172 http://www.osvdb.org/4172 Availability ============ This GLSA and any updates to it are available for viewing at the Gentoo Security Website: http://security.gentoo.org/glsa/glsa-200409-03.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.
