    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)

    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.

      These files will probably be moved into the stable distribution on
      its next update.
