Paket:
gimp 2.x
Operacijski sustavi:
Red Hat Enterprise Linux 4
Kritičnost:
7.5
Problem:
cjelobrojno prepisivanje, pogreška u programskoj komponenti, preljev međuspremnika
U dodacima BMP i PCX dolazi do greške koja uzrokuje cjelobrojno prepisivanje, dok u dodatku PSP i filtru slika Sphere Designer dolazi do preljeva međuspremnika.
Posljedica:
Podmetanjem posebno oblikovanih datoteka moguće je udaljeno izvođenje DoS napada i pokretanje proizvoljnog programskog koda.

3. Description:
The GIMP (GNU Image Manipulation Program) is an image composition and
editing program.
An integer overflow flaw, leading to a heap-based buffer overflow, was
found in the GIMP's Microsoft Windows Bitmap (BMP) and Personal Computer
eXchange (PCX) image file plug-ins. An attacker could create a
specially-crafted BMP or PCX image file that, when opened, could cause the
relevant plug-in to crash or, potentially, execute arbitrary code with the
privileges of the user running the GIMP. (CVE-2009-1570, CVE-2011-1178)
A heap-based buffer overflow flaw was found in the GIMP's Paint Shop Pro
(PSP) image file plug-in. An attacker could create a specially-crafted PSP
image file that, when opened, could cause the PSP plug-in to crash or,
potentially, execute arbitrary code with the privileges of the user running
the GIMP. (CVE-2010-4543)
A stack-based buffer overflow flaw was found in the GIMP's Sphere Designer
image filter. An attacker could create a specially-crafted Sphere Designer
filter configuration file that, when opened, could cause the Sphere
Designer plug-in to crash or, potentially, execute arbitrary code with the
privileges of the user running the GIMP. (CVE-2010-4541)
Red Hat would like to thank Stefan Cornelius of Secunia Research for
responsibly reporting the CVE-2009-1570 flaw.
Users of the GIMP are advised to upgrade to these updated packages, which
contain backported patches to correct these issues. The GIMP must be
restarted for the update to take effect.
