"Joachim Schrod discovered several buffer overflow vulnerabilities and an insecure temporary file creation in the "dvilj" application that is used by dvips to convert DVI files to printer formats (CVE-2007-5937, CVE-2007-5936). Bastien Roucaries reported that the "dvips" application is vulnerable to two stack-based buffer overflows when processing DVI documents with long \href{} URIs (CVE-2007-5935). teTeX also includes code from Xpdf that is vulnerable to a memory corruption and two heap-based buffer overflows (GLSA 200711-22); and it contains code from T1Lib that is vulnerable to a buffer overflow when processing an overly long font filename (GLSA 200710-12).
[...]
A remote attacker could entice a user to process a specially crafted DVI or PDF file which could lead to the execution of arbitrary code with the privileges of the user running the application. A local attacker could exploit the "dvilj" vulnerability to conduct a symlink attack to overwrite arbitrary files."

Since according to packages.ubuntu.com some parts of tetex are part of Ubuntu's main component, I shamelessly copied over Gentoo's GLSA.
