Debian DSA-3642-1 : lighttpd - security update

high Nessus Plugin ID 92955

Language:

Synopsis

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

Description

Dominic Scheirlinck and Scott Geary of Vend reported insecure behavior in the lighttpd web server. Lighttpd assigned Proxy header values from client requests to internal HTTP_PROXY environment variables, allowing remote attackers to carry out Man in the Middle (MITM) attacks or initiate connections to arbitrary hosts.

Solution

Upgrade the lighttpd packages.

For the stable distribution (jessie), this problem has been fixed in version 1.4.35-4+deb8u1.
