Package        : analog
Vulnerability  : Buffer overflow
Type           : Remote exploit
Debian-specific: no

The author of analog, Stephen Turner, has found a buffer overflow bug
in all versions of analog except of version 4.16.  A malicious user
could use an ALIAS command to construct very long strings which were
not checked for length and boundaries.  This bug is particularly
dangerous if the form interface (which allows unknown users to run the
program via a CGI script) has been installed.  There doesn't seem to
be a known exploit.

The bugfix has been backported to the version of analog from Debian
2.2.  Version 4.01-1potato1 is fixed.

We recommend you upgrade your analog packages 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.
