Debian DSA-1362-2 : lighttpd - several vulnerabilities

High Nessus Plugin ID 25962

Synopsis

The remote Debian host is missing a security-related update.

Description

Several vulnerabilities were discovered in lighttpd, a fast webserver with minimal memory footprint, which could allow the execution of arbitrary code via the overflow of CGI variables when mod_fcgi was enabled. The Common Vulnerabilities and Exposures project identifies the following problems :

- CVE-2007-3946 The use of mod_auth could leave to a denial of service attack crashing the webserver.

- CVE-2007-3947 The improper handling of repeated HTTP headers could cause a denial of service attack crashing the webserver.

- CVE-2007-3949 A bug in mod_access potentially allows remote users to bypass access restrictions via trailing slash characters.

- CVE-2007-3950 On 32-bit platforms users may be able to create denial of service attacks, crashing the webserver, via mod_webdav, mod_fastcgi, or mod_scgi.

Solution

Upgrade the lighttpd package.

For the stable distribution (etch), these problems have been fixed in version 1.4.13-4etch4.
