Background ========== Lighttpd is a lightweight HTTP web server. Affected packages ================= ------------------------------------------------------------------- Package / Vulnerable / Unaffected ------------------------------------------------------------------- 1 www-servers/lighttpd < 1.4.14 >= 1.4.14 Description =========== Robert Jakabosky discovered an infinite loop triggered by a connection abort when Lighttpd processes carriage return and line feed sequences. Marcus Rueckert discovered a NULL pointer dereference when a server running Lighttpd tries to access a file with a mtime of 0. Impact ====== A remote attacker could upload a specially crafted file to the server or send a specially crafted request and then abort the connection, possibly resulting in a crash or a Denial of Service by CPU consumption. 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-1.4.14" References ========== [ 1 ] CVE-2007-1869 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2007-1869 [ 2 ] CVE-2007-1870 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2007-1870 Availability ============ This GLSA and any updates to it are available for viewing at the Gentoo Security Website: http://security.gentoo.org/glsa/glsa-200705-07.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.
