Debian Security Advisory DSA-1917-1                              Giuseppe Iuculano
October 24, 2009

Package        : mimetex
Vulnerability  : several vulnerabilities
Problem type   : remote (local)
Debian-specific: no
Debian bug     : 537254
CVE Ids        : CVE-2009-1382 CVE-2009-2459

Several vulnerabilities have been discovered in mimetex, a lightweight
alternative to MathML. The Common Vulnerabilities and Exposures project
identifies the following problems:


Chris Evans and Damien Miller, discovered multiple stack-based buffer overflow.
An attacker could execute arbitrary code via a TeX file with long picture,
circle, input tags.


Chris Evans discovered that mimeTeX contained certain directives that may be
unsuitable for handling untrusted user input. A remote attacker can obtain
sensitive information.

For the oldstable distribution (etch), these problems have been fixed in
version 1.50-1+etch1.

Due to a bug in the archive system, the fix for the stable distribution
(lenny) will be released as version 1.50-1+lenny1 once it is available.

For the testing distribution (squeeze), and the unstable distribution (sid),
these problems have been fixed in version 1.50-1.1.

We recommend that you upgrade your mimetex packages.
