New! Vulnerability Priority Rating (VPR)

Tenable calculates a dynamic VPR for every vulnerability. VPR combines vulnerability information with threat intelligence and machine learning algorithms to predict which vulnerabilities are most likely to be exploited in attacks. Read more about what VPR is and how it's different from CVSS.

Synopsis

The remote Gentoo host is missing one or more security-related patches.

Description

The remote host is affected by the vulnerability described in GLSA-200711-26 (teTeX: Multiple vulnerabilities)

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).
Impact :

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.
Workaround :

There is no known workaround at this time.

Solution

All teTeX users should upgrade to the latest version:
# emerge --sync # emerge --ask --oneshot --verbose '>=app-text/tetex-3.0_p1-r6'
