Detail

Synopsis

Multiple vulnerabilities in lighttpd may lead to information disclosure or a Denial of Service.

Background

lighttpd is a lightweight high-performance web server.

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"
