Background ========== lighttpd is a lightweight high-performance web server. Affected packages ================= ------------------------------------------------------------------- Package / Vulnerable / Unaffected ------------------------------------------------------------------- 1 www-servers/lighttpd < 1.4.19-r2 >= 1.4.19-r2 Description =========== Julien Cayzax discovered that an insecure default setting exists in mod_userdir in lighttpd. When userdir.path is not set the default value used is $HOME. It should be noted that the "nobody" user's $HOME is "/" (CVE-2008-1270). An error also exists in the SSL connection code which can be triggered when a user prematurely terminates his connection (CVE-2008-1531). Impact ====== A remote attacker could exploit the first vulnerability to read arbitrary files. The second vulnerability can be exploited by a remote attacker to cause a Denial of Service by terminating a victim's SSL connection. Workaround ========== As a workaround for CVE-2008-1270 you can set userdir.path to a sensible value, e.g. "public_html". Resolution ========== All lighttpd users should upgrade to the latest version: # emerge --sync # emerge --ask --oneshot --verbose ">=www-servers/lighttpd-1.4.19-r2" References ========== [ 1 ] CVE-2008-1270 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2008-1270 [ 2 ] CVE-2008-1531 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2008-1531 Availability ============ This GLSA and any updates to it are available for viewing at the Gentoo Security Website: http://security.gentoo.org/glsa/glsa-200804-08.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.
