Debian Security Advisory DSA 1704-2                    security@debian.org

Package        : netatalk
Vulnerability  : arbitrary code execution
Problem type   : remote
Debian-specific: no
CVE ID         : CVE-2008-5718
Debian Bug     : 510585

The update in DSA 1704-1 was incomplete as it missed to escape a few
important characters which enabled an attacker to overwrite arbitrary
files.

It was discovered that netatalk, an implementation of the AppleTalk
suite, is affected by a command injection vulnerability when processing
PostScript streams via papd.  This is leading to arbitrary remote
code execution.  Note that this only affects installations that are
configured to use a pipe command in combination with wildcard symbols
substituted with values of the printed job.

For the stable distribution (etch) this problem has been fixed in
version 2.0.3-4+etch2.

For the unstable distribution (sid) this problem has been fixed in
version 2.0.4~beta2-1.1.

We recommend that you upgrade your netatalk 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 at the end of this advisory:

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 4.0 alias etch
- -------------------------------

Stable updates are available for alpha, amd64, arm, hppa, i386, ia64, mips, mipsel, powerpc, s390 and sparc.
