Debian Security Advisory DSA 122-1                     security () debian org

Package        : zlib, various
Vulnerability  : malloc error (double free)
Problem-Type   : potential remote root
Debian-specific: no

The compression library zlib has a flaw in which it attempts to free
memory more than once under certain conditions. This can possibly be
exploited to run arbitrary code in a program that includes zlib. If a
network application running as root is linked to zlib, this could
potentially lead to a remote root compromise. No exploits are known at
this time. This vulnerability is assigned the CVE candidate name of
CAN-2002-0059.

The zlib vulnerability is fixed in the Debian zlib package version
1.1.3-5.1. A number of programs either link statically to zlib or include
a private copy of zlib code. These programs must also be upgraded
to eliminate the zlib vulnerability. The affected packages and fixed
versions follow:
  amaya 2.4-1potato1
  dictd 1.4.9-9potato1
  erlang 49.1-10.1
  freeamp 2.0.6-2.1
  mirrordir 0.10.48-2.1
  ppp 2.3.11-1.5
  rsync 2.3.2-1.6
  vrweb 1.5-5.1

Those using the pre-release (testing) version of Debian should upgrade
to zlib 1.1.3-19.1 or a later version. Note that since this version of
Debian has not yet been released it may not be available immediately for
all architectures. Debian 2.2 (potato) is the latest supported release.

We recommend that you upgrade your packages immediately. Note that you
should restart all programs that use the shared zlib library in order
for the fix to take effect. This is most easily done by rebooting the
system.

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.
