Background ========== PECL Alternative PHP Cache (PECL APC) is a free, open, and robust framework for caching and optimizing PHP intermediate code. Affected packages ================= ------------------------------------------------------------------- Package / Vulnerable / Unaffected ------------------------------------------------------------------- 1 dev-php5/pecl-apc < 3.0.16-r1 >= 3.0.16-r1 Description =========== Daniel Papasian discovered a stack-based buffer overflow in the apc_search_paths() function in the file apc.c when processing long filenames. Impact ====== A remote attacker could exploit this vulnerability to execute arbitrary code in PHP applications that pass user-controlled input to the include() function. Workaround ========== There is no known workaround at this time. Resolution ========== All PECL APC users should upgrade to the latest version: # emerge --sync # emerge --ask --oneshot --verbose ">=dev-php5/pecl-apc-3.0.16-r1" References ========== [ 1 ] CVE-2008-1488 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2008-1488 Availability ============ This GLSA and any updates to it are available for viewing at the Gentoo Security Website: http://security.gentoo.org/glsa/glsa-200804-07.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.
