Posted by LinuxSecurity.com Team   
Debian There is a buffer overflow in log2mail. A specially crafted (remote) log message could overflow a static buffer, potentially leaving log2mail to execute arbitrary code as root.

Package        : log2mail
Vulnerability  : buffer overflow
Problem-Type   : remote, local
Debian-specific: no

Enrico Zini discovered a buffer overflow in log2mail, a daemon for
watching logfiles and sending lines with matching patterns via mail.
The log2mail daemon is started upon system boot and runs as root.  A
specially crafted (remote) log message could overflow a static buffer,
potentially leaving log2mail to execute arbitrary code as root.

This problem has been fixed in version 0.2.5.1 the current
stable distribution (woody) and in version  for the unstable
distribution (sid).  The old stable distribution (potato) is not
affected since it doesn't contain a log2mail package

We recommend that you upgrade your log2mail package.

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.
