Package        : pound
Vulnerability  : several
Problem-Type   : remote
Debian-specific: no
CVE ID         : CVE-2005-1391 CVE-2005-3751
Debian Bug     : 307852

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.
