Background ========== Texinfo is the official documentation system of the GNU project. Affected packages ================= ------------------------------------------------------------------- Package / Vulnerable / Unaffected ------------------------------------------------------------------- 1 sys-apps/texinfo < 4.8-r5 >= 4.8-r5 Description =========== Miloslav Trmac from Red Hat discovered a buffer overflow in the "readline()" function of texindex.c. The "readline()" function is called by the texi2dvi and texindex commands. Impact ====== By enticing a user to open a specially crafted Texinfo file, an attacker could execute arbitrary code with the rights of the user running Texinfo. Workaround ========== There is no known workaround at this time. Resolution ========== All Texinfo users should upgrade to the latest version: # emerge --sync # emerge --ask --oneshot --verbose ">=sys-apps/texinfo-4.8-r5" References ========== [ 1 ] CVE-2006-4810 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2006-4810 Availability ============ This GLSA and any updates to it are available for viewing at the Gentoo Security Website: http://security.gentoo.org/glsa/glsa-200611-16.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.
