Background ========== teTex is a complete TeX distribution. It is used for creating and manipulating LaTeX documents. CSTeX is a TeX distribution with Czech and Slovak support. pTeX is and ASCII publishing TeX distribution. Affected packages ================= ------------------------------------------------------------------- Package / Vulnerable / Unaffected ------------------------------------------------------------------- 1 app-text/tetex < 2.0.2-r8 >= 2.0.2-r8 2 app-text/cstetex < 2.0.2-r2 >= 2.0.2-r2 3 app-text/ptex < 3.1.5-r1 >= 3.1.5-r1 ------------------------------------------------------------------- 3 affected packages on all of their supported architectures. ------------------------------------------------------------------- Description =========== CSTeX, teTex, and pTeX include XPdf code to handle PDF files. This XPdf code is vulnerable to several heap overflows (GLSA 200512-08) as well as several buffer and integer overflows discovered by Chris Evans (CESA-2005-003). Impact ====== An attacker could entice a user to open a specially crafted PDF file with teTeX, pTeX or CSTeX, potentially resulting in the execution of arbitrary code with the rights of the user running the affected application. 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-2.0.2-r8" All CSTeX users should upgrade to the latest version: # emerge --sync # emerge --ask --oneshot --verbose ">=app-text/cstetex-2.0.2-r2" All pTeX users should upgrade to the latest version: # emerge --sync # emerge --ask --oneshot --verbose ">=app-text/ptex-3.1.5-r1" References ========== [ 1 ] CVE-2005-3193 http://www.cve.mitre.org/cgi-bin/cvename.cgi?name=CAN-2005-3193 [ 2 ] GLSA 200512-08 http://www.gentoo.org/security/en/glsa/glsa-200512-08.xml [ 3 ] CESA-2005-003 http://scary.beasts.org/security/CESA-2005-003.txt Availability ============ This GLSA and any updates to it are available for viewing at the Gentoo Security Website: http://security.gentoo.org/glsa/glsa-200603-02.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.
