Debian: New polipo packages fix denial of service

Several denial of service vulnerabilities have been discovered in polipo, a small, caching web proxy. A malicous remote sever could cause polipo to crash by sending an invalid Cache-Control header. A malicous client could cause polipo to crash by sending a large Content-Length value. Updated packages are available from security.debian.org.

Package        : polipo
Vulnerability  : denial of service
Problem type   : remote
Debian-specific: no

Debian bug     : 547047 560779

Several denial of service vulnerabilities have been discovered in polipo, a
small, caching web proxy. The Common Vulnerabilities and Exposures project
identifies the following problems:

CVE-2009-3305

   A malicous remote sever could cause polipo to crash by sending an
   invalid Cache-Control header.

CVE-2009-4143

   A malicous client could cause polipo to crash by sending a large
   Content-Length value.

This upgrade also fixes some other bugs that could lead to a daemon crash
or an infinite loop and may be triggerable remotely.

For the stable distribution (lenny), these problems have been fixed in
version 1.0.4-1+lenny1.

For the testing distribution (squeeze) and the unstable distribution (sid),
these problems have been fixed in version 1.0.4-3.


We recommend that you upgrade your polipo packages.
