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 https://www.cve.org/CVERecord?id=CVE-2006-3119 Availability =========== This GLSA and any updates to it are available for viewing at the Gentoo Security Website: https://security.gentoo.org/glsa/200608-22 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.

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 https://www.cve.org/CVERecord?id=CVE-2006-1695 Availability =========== This GLSA and any updates to itare available for viewing at the Gentoo Security Website: https://security.gentoo.org/glsa/200604-13 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.
