Background ========== fbida is a collection of image viewers and editors for the framebuffer console and X11. fbgs is a PostScript and PDF viewer for the linux framebuffer console. Affected packages ================= ------------------------------------------------------------------- Package / Vulnerable / Unaffected ------------------------------------------------------------------- 1 media-gfx/fbida < 2.03-r4 >= 2.03-r4 Description =========== Toth Andras has discovered a typographic mistake in the "fbgs" script, shipped with fbida if the "fbcon" and "pdf" USE flags are both enabled. This script runs "gs" without the -dSAFER option, thus allowing a PostScript file to execute, delete or create any kind of file on the system. Impact ====== A remote attacker can entice a vulnerable user to view a malicious PostScript or PDF file with fbgs, which may result with the execution of arbitrary code. Workaround ========== There is no known workaround at this time. Resolution ========== All fbida users with the "fbcon" and "pdf" USE flags both enabled should upgrade to the latest version: # emerge --sync # emerge --ask --oneshot --verbose ">=media-gfx/fbida-2.03-r4" References ========== [ 1 ] CVE-2006-3119 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2006-3119 Availability ============ This GLSA and any updates to it are available for viewing at the Gentoo Security Website: http://security.gentoo.org/glsa/glsa-200608-22.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.
