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 Description =========== 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" References ========== [ 1 ] CVE-2007-5935 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2007-5935 [ 2 ] CVE-2007-5936 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2007-5936 [ 3 ] CVE-2007-5937 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2007-5937 [ 4 ] GLSA 200710-12 http://www.gentoo.org/security/en/glsa/glsa-200710-12.xml [ 5 ] GLSA 200711-22 http://www.gentoo.org/security/en/glsa/glsa-200711-22.xml Availability ============ This GLSA and any updates to it are available for viewing at the Gentoo Security Website: http://security.gentoo.org/glsa/glsa-200711-26.xml Concerns? ========= Security is a primary focus of Gentoo Linux and ensuring the confidentiality and security of our users machines is of utmost importance to us.
