"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).

Note that Tenable Network Security has extracted the preceding
description block directly from the Ubuntu security advisory. Tenable
has attempted to automatically clean and format it as much as possible
without introducing additional issues."
