Background ========== PHP is a widely-used general-purpose scripting language that is especially suited for Web development and can be embedded into HTML. Affected packages ================= ------------------------------------------------------------------- Package / Vulnerable / Unaffected ------------------------------------------------------------------- 1 dev-lang/php < 5.1.6-r6 *>= 4.4.4-r6 >= 5.1.6-r6 Description =========== A flaw in the PHP memory handling routines allows an unserialize() call to be executed on non-allocated memory due to a previous integer overflow. Impact ====== An attacker could execute arbitrary code with the rights of the web server user or the user running a vulnerable PHP script. Workaround ========== There is no known workaround at this time. Resolution ========== All PHP 5.x users should upgrade to the latest version: # emerge --sync # emerge --ask --oneshot --verbose ">=dev-lang/php-5.1.6-r6" All PHP 4.x users should upgrade to the latest version: # emerge --sync # emerge --ask --oneshot --verbose ">=dev-lang/php-4.4.4-r6" References ========== [ 1 ] CVE-2006-4812 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2006-4812 Availability ============ This GLSA and any updates to it are available for viewing at the Gentoo Security Website: http://security.gentoo.org/glsa/glsa-200610-14.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.
