Background ========== mod_fcgid is a binary-compatible alternative to mod_fastcgi with better process management. Affected packages ================= ------------------------------------------------------------------- Package / Vulnerable / Unaffected ------------------------------------------------------------------- 1 www-apache/mod_fcgid < 2.3.7 >= 2.3.7 Description =========== Multiple vulnerabilities have been found in mod_fcgid: * An error in the "fcgid_header_bucket_read()" function in fcgid_bucket.c could cause a stack-based buffer overflow (CVE-2010-3872). * An error in the "is_spawn_allowed() function in fcgid_spawn_ctl.c prevents Apache from recognizing the FcgidMaxProcessesPerClass directive for a virtual host (CVE-2012-1181). Impact ====== A local attacker could possibly execute arbitrary code with the privileges of the process or cause a Denial of Service condition. Furthermore, a remote attacker could send specially crafted HTTP requests, possibly resulting in a Denial of Service condition. Workaround ========== There is no known workaround at this time. Resolution ========== All mod_fcgid users should upgrade to the latest version: # emerge --sync # emerge --ask --oneshot --verbose ">=www-apache/mod_fcgid-2.3.7" References ========== [ 1 ] CVE-2010-3872 http://nvd.nist.gov/nvd.cfm?cvename=CVE-2010-3872 [ 2 ] CVE-2012-1181 http://nvd.nist.gov/nvd.cfm?cvename=CVE-2012-1181 Availability ============ This GLSA and any updates to it are available for viewing at the Gentoo Security Website: http://security.gentoo.org/glsa/glsa-201207-09.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.
