Debian Security Advisory DSA 145-1                     security@debian.org

Package        : tinyproxy
Vulnerability  : doubly freed memory
Problem-Type   : remote
Debian-specific: no
Bugtraq Id     : 4731

The authors of tinyproxy, a lightweight HTTP proxy, discovered a bug
in the handling of some invalid proxy requests.  Under some
circumstances, an invalid request may result in a allocated memory
being freed twice.  This can potentially result in the execution of
arbitrary code.

This problem has been fixed in version 1.4.3-2woody2 for the current
stable distribution (woody) and in version 1.4.3-3 for the unstable
distribution (sid).  The old stable distribution (potato) is not
affected by this problem.

We recommend that you upgrade your tinyproxy package immediately.

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.
