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.
