Package        : pidgin
Vulnerability  : programming error
Problem type   : remote
Debian-specific: no
CVE Id(s)      : CVE-2009-3615

It was discovered that incorrect pointer handling in the purple library,
an internal component of the multi-protocol instant messaging client
Pidgin, could lead to denial of service or the execution of arbitrary
code through malformed contact requests.

For the stable distribution (lenny), this problem has been fixed in
version 2.4.3-4lenny5.

For the unstable distribution (sid), this problem has been fixed in
version 2.6.3-1.

We recommend that you upgrade your pidgin package.

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.


Debian GNU/Linux 5.0 alias lenny
