More information:

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.

Fixed in:

Debian GNU/Linux 5.0 (lenny)
