Background ========== HAProxy is a TCP/HTTP reverse proxy for high availability environments. Affected packages ================= ------------------------------------------------------------------- Package / Vulnerable / Unaffected ------------------------------------------------------------------- 1 net-proxy/haproxy < 1.4.21 >= 1.4.21 Description =========== A boundary error in HAProxy could cause a buffer overflow when header rewriting is enabled and the configuration sets global.tune.bufsize to a value greater than the default (16384 bytes). Impact ====== A remote attacker could possibly execute arbitrary code with the privileges of the process or cause a Denial of Service condition. Workaround ========== There is no known workaround at this time. Resolution ========== All HAProxy users should upgrade to the latest version: # emerge --sync # emerge --ask --oneshot --verbose ">=net-proxy/haproxy-1.4.21" References ========== [ 1 ] CVE-2012-2942 http://nvd.nist.gov/nvd.cfm?cvename=CVE-2012-2942 Availability ============ This GLSA and any updates to it are available for viewing at the Gentoo Security Website: http://security.gentoo.org/glsa/glsa-201301-02.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.
