Debian Security Advisory DSA-028-1                       security@debian.org 
http://www.debian.org/security/                               Martin Schulze

Package        : man-db
Vulnerability  : format string vulnerability
Type           : local exploit
Debian-specific: no

Styx has reported that the program `man' mistakenly passes malicious
strings (i.e. containing format characters) through routines that were
not meant to use them as format strings.  Since this could cause a
segmentation fault and privileges were not dropped it may lead to an
exploit for the 'man' user.

We recommend you upgrade your man-db package immediately.

wget url
        will fetch the file for you
dpkg -i file.deb
        will install the referenced file.

You may use an automated update by adding the resources from the
footer to the proper configuration.


Debian GNU/Linux 2.2 alias potato
------------------------------------

  Potato was released for the alpha, arm, i386, m68k, powerpc and sparc
  architectures.
