Otkrivena je ranjivost u paketu libjpeg-turbo koja zlonamjernim korisnicima omogućava izvršavanje proizvoljnog programskog koda ili izvođenje DoS napada rušenjem aplikacije.
Ranjivost se javlja pri dekomprimiranju pojedinih zlonamjerno oblikovanih JPEG datoteka.
Posljedica:
Zlonamjerni korisnici, ukoliko podmetnu posebno oblikovanu JPEG datoteku, bi mogli pokrenuti proizvoljan programski kod s pravima korisnika koji pokreće aplikaciju i izvesti DoS (eng. Denial of Service) napad.
Rješenje:
Svim se korisnicima, u svrhu zaštite, savjetuje nadogradnja na najnoviju inačicu.

Mandriva Linux Security Advisory MDVSA-2012:121
http://www.mandriva.com/security/
_______________________________________________________________________
Package : libjpeg-turbo
Date : August 1, 2012
Affected: 2011.
_______________________________________________________________________
Problem Description:
A vulnerability has been discovered and corrected in libjpeg-turbo:
A Heap-based buffer overflow was found in the way libjpeg-turbo
decompressed certain corrupt JPEG images in which the component
count was erroneously set to a large value. An attacker could create
a specially-crafted JPEG image that, when opened, could cause an
application using libpng to crash or, possibly, execute arbitrary
code with the privileges of the user running the application
(CVE-2012-2806).
The updated packages have been patched to correct this issue.
