Background ========== Lighttpd is a lightweight HTTP web server. Affected packages ================= ------------------------------------------------------------------- Package / Vulnerable / Unaffected ------------------------------------------------------------------- 1 www-servers/lighttpd < 1.4.16 >= 1.4.16 Description =========== Stefan Esser discovered errors with evidence of memory corruption in the code parsing the headers. Several independent researchers also reported errors involving the handling of HTTP headers, the mod_auth and mod_scgi modules, and the limitation of active connections. Impact ====== A remote attacker can trigger any of these vulnerabilities by sending malicious data to the server, which may lead to a crash or memory exhaustion, and potentially the execution of arbitrary code. Additionally, access-deny settings can be evaded by appending a final / to a URL. Workaround ========== There is no known workaround at this time. Resolution ========== All Lighttpd users should upgrade to the latest version: # emerge --sync # emerge --ask --oneshot --verbose ">=www-servers/lighttpd-1.4.16" References ========== [ 1 ] CVE-2007-3946 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2007-3946 [ 2 ] CVE-2007-3947 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2007-3947 [ 3 ] CVE-2007-3948 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2007-3948 [ 4 ] CVE-2007-3949 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2007-3949 [ 5 ] CVE-2007-3950 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2007-3950 Availability ============ This GLSA and any updates to it are available for viewing at the Gentoo Security Website: http://security.gentoo.org/glsa/glsa-200708-11.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.
