Background ========== enscript is a powerful ASCII to PostScript file converter. Affected packages ================= ------------------------------------------------------------------- Package / Vulnerable / Unaffected ------------------------------------------------------------------- 1 app-text/enscript < 1.6.4-r4 >= 1.6.4-r4 Description =========== Two stack-based buffer overflows in the read_special_escape() function in src/psgen.c have been reported. Ulf Harnhammar of Secunia Research discovered a vulnerability related to the "setfilename" command (CVE-2008-3863), and Kees Cook of Ubuntu discovered a vulnerability related to the "font" escape sequence (CVE-2008-4306). Impact ====== An attacker could entice a user or automated system to process specially crafted input with the special escapes processing enabled using the "-e" option, possibly resulting in the execution of arbitrary code. Workaround ========== There is no known workaround at this time. Resolution ========== All enscript users should upgrade to the latest version: # emerge --sync # emerge --ask --oneshot --verbose ">=app-text/enscript-1.6.4-r4" References ========== [ 1 ] CVE-2008-3863 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2008-3863 [ 2 ] CVE-2008-4306 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2008-4306 Availability ============ This GLSA and any updates to it are available for viewing at the Gentoo Security Website: http://security.gentoo.org/glsa/glsa-200812-02.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.
