FreeBSD : lighttpd -- Remote DOS in CRLF parsing (d2b48d30-ea97-11db-a802-000fea2763ce)

medium Nessus Plugin ID 25052

Synopsis

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

Description

Lighttpd SA :

If the connection aborts during parsing '\r\n\r\n' the server might get into a infinite loop and use 100% of the CPU time. lighttpd still responses to other requests. This can be repeated until either the server limit for concurrent connections or file descriptors is reached.

The bug was reported and fixed by Robert Jakabosky.

Solution

Update the affected package.
