Gentoo: GLSA-200711-26: teTeX: Multiple vulnerabilities
Summary
-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Gentoo Linux Security Advisory GLSA 200711-26 https://security.gentoo.org/
Severity: Normal Title: teTeX: Multiple vulnerabilities Date: November 18, 2007 Bugs: #198238 ID: 200711-26
Synopsis ======= Multiple vulnerabilities have been discovered in teTeX, possibly allowing to execute arbitrary code or overwrite arbitrary files.
Background ========= teTeX is a complete TeX distribution for editing documents.
Affected packages ================ ------------------------------------------------------------------- Package / Vulnerable / Unaffected ------------------------------------------------------------------- 1 app-text/tetex < 3.0_p1-r6 >= 3.0_p1-r6
========== 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.
Resolution ========= All teTeX users should upgrade to the latest version:
# emerge --sync # emerge --ask --oneshot --verbose ">=app-text/tetex-3.0_p1-r6"
