Debian Security Advisory
DSA-1884-1 nginx -- buffer underflow
- Date Reported:
- 14 Sep 2009
- Affected Packages:
- nginx
- Vulnerable:
- Yes
- Security database references:
- In Mitre's CVE dictionary: CVE-2009-2629.
- More information:
-
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.
