Debian DSA-1884-1 : nginx - buffer underflow

high Nessus Plugin ID 44749

Language:

Synopsis

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

Description

Chris Ries discovered that nginx, a high-performance HTTP server, reverse proxy and IMAP/POP3 proxy server, is vulnerable to a buffer underflow when processing certain HTTP requests. An attacker can use this to execute arbitrary code with the rights of the worker process (www-data on Debian) or possibly perform denial of service attacks by repeatedly crashing worker processes via a specially crafted URL in an HTTP request.

Solution

Upgrade the nginx packages.

For the oldstable distribution (etch), this problem has been fixed in version 0.4.13-2+etch2.

For the stable distribution (lenny), this problem has been fixed in version 0.6.32-3+lenny2.
