More information:

Two vulnerabilities have been discovered in Pound, a reverse proxy and load balancer for HTTP. The Common Vulnerabilities and Exposures project identifies the following problems:

  • CVE-2005-1391:

    Overly long HTTP Host: headers may trigger a buffer overflow in the add_port() function, which may lead to the execution of arbitrary code.

  • CVE-2005-3751:

    HTTP requests with conflicting Content-Length and Transfer-Encoding headers could lead to HTTP Request Smuggling Attack, which can be exploited to bypass packet filters or poison web caches.

The old stable distribution (woody) does not contain pound packages.

For the stable distribution (sarge) these problems have been fixed in version 1.8.2-1sarge1.

For the unstable distribution (sid) these problems have been fixed in version 1.9.4-1.

We recommend that you upgrade your pound package.

Fixed in:

Debian GNU/Linux 3.1 (sarge)
