Subject: [SECURITY] [DSA 1884-1] New nginx packages fix arbitrary code execution
-----BEGIN PGP SIGNED MESSAGE-----
Hash: SHA1
- --------------------------------------------------------------------------
Debian Security Advisory DSA-1884-1 security@...ian.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.
Upgrade instructions
- --------------------
wget url
will fetch the file for you
dpkg -i file.deb
will install the referenced file.
If you are using the apt-get package manager, use the line for
sources.list as given below:
apt-get update
will update the internal database
apt-get upgrade
will install corrected packages
You may use an automated update by adding the resources from the
footer to the proper configuration.
