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.
