==========================================================
A security issue affects the following Ubuntu releases:

Ubuntu 8.04 LTS
Ubuntu 8.10
Ubuntu 9.04

This advisory also applies to the corresponding versions of
Kubuntu, Edubuntu, and Xubuntu.

The problem can be corrected by upgrading your system to the
following package versions:

Ubuntu 8.04 LTS:
  mimetex                         1.50-1ubuntu0.8.04.1

Ubuntu 8.10:
  mimetex                         1.50-1ubuntu0.8.10.1

Ubuntu 9.04:
  mimetex                         1.50-1ubuntu0.9.04.1

In general, a standard system upgrade is sufficient to effect the
necessary changes.

Details follow:

Chris Evans discovered that mimeTeX incorrectly handled certain long tags.
An attacker could exploit this with a crafted mimeTeX expression and cause
a denial of service or possibly execute arbitrary code. (CVE-2009-1382)

Chris Evans discovered that mimeTeX contained certain directives that may
be unsuitable for handling untrusted user input. This update fixed the
issue by disabling the \input and \counter tags. (CVE-2009-2459)
