Synopsis ========
Multiple vulnerabilities in lighttpd may lead to information disclosure or a Denial of Service.
Background ==========
lighttpd is a lightweight high-performance web server.
Affected packages =================
------------------------------------------------------------------- Package / Vulnerable / Unaffected ------------------------------------------------------------------- 1 www-servers/lighttpd < 1.4.19-r2 >=3D 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 ">=3Dwww-servers/lighttpd-1.4.19-r= 2"
