Description:
Mattias Bengtsson and Philip Olausson have reported a vulnerability in lighttpd, which can be exploited by malicious people to compromise a vulnerable system.

The vulnerability is caused due to an error in the mod_fastcgi extension when handling headers in a HTTP request. This can be exploited to e.g. add or replace PHP headers (e.g. SCRIPT_FILENAME) via a HTTP request containing an overly long header.

Successful exploitation allows execution of arbitrary PHP code.

The vulnerability affects versions prior to 1.4.18.
