Debian Security Advisory DSA-1884-1 security@debian.org
http://www.debian.org/security/ Nico Golde
September 14th, 2009 http://www.debian.org/security/faq
- - --------------------------------------------------------------------------
Package : nginx
Vulnerability : buffer underflow
Problem type : remote
Debian-specific: no
CVE ID : CVE-2009-2629
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.
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.
For the testing distribution (squeeze), this problem will be fixed soon.
For the unstable distribution (sid), this problem has been fixed in
version 0.7.61-3.
We recommend that you upgrade your nginx packages.
