Background ========== fbida is a collection of image viewers and editors for the framebuffer console and X11. Affected packages ================= ------------------------------------------------------------------- Package / Vulnerable / Unaffected ------------------------------------------------------------------- 1 media-gfx/fbida < 2.03-r3 >= 2.03-r3 Description =========== Jan Braun has discovered that the "fbgs" script provided by fbida insecurely creates temporary files in the "/var/tmp" directory. Impact ====== A local attacker could create links in the temporary file directory, pointing to a valid file somewhere on the filesystem. When an affected script is called, this could result in the file being overwritten with the rights of the user running the script. Workaround ========== There is no known workaround at this time. Resolution ========== All fbida users should upgrade to the latest version: # emerge --sync # emerge --ask --oneshot --verbose ">=media-gfx/fbida-2.03-r3" References ========== [ 1 ] CVE-2006-1695 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2006-1695 Availability ============ This GLSA and any updates to it are available for viewing at the Gentoo Security Website: http://security.gentoo.org/glsa/glsa-200604-13.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.
