Synopsis ========
The fbgs script provided by fbida allows the execution of arbitrary code.
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"
