Package        : polipo
Vulnerability  : denial of service
Problem type   : remote
Debian-specific: no
CVE Id(s)      : CVE-2009-3305 CVE-2009-4413
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:


    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.

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.

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.
