Ispravljena su dva nova sigurnosna propusta u radu programskog paketa libvorbis. Udaljeni ih napadač može iskoristiti za napad uskraćivanjem usluga (DoS) te izvršavanje proizvoljnog programskog koda.
Sigurnosne ranjivosti se javljaju zbog neodgovarajuće inicijalizacije nsChildView struktura podataka te zbog višestrukih nespecificiranih pogrešaka.
Posljedica:
Udaljeni napadač navedene ranjivosti može iskoristiti za proizvoljno pokretanje programskog koda te DoS (eng. Denial of Service) napad podmetanjem posebno oblikovane Ogg Vorbis datoteke.
Rješenje:
Rješenje problema sigurnosti je nadogradnja paketa na novije inačice.

Package : libvorbis
Date : April 3, 2012
Affected: Enterprise Server 5.0
_______________________________________________________________________
Problem Description:
Multiple vulnerabilities has been found and corrected in libvorbis:
A specially-crafted Ogg Vorbis media format file (Ogg) could cause an
application using libvorbis to crash or, possibly, execute arbitrary
code when opened (CVE-2009-3379).
If a specially-crafted Ogg Vorbis media file was opened by an
application using libvorbis, it could cause the application to crash
or, possibly, execute arbitrary code with the privileges of the user
running the application (CVE-2012-0444).
The updated packages have been patched to correct these issues.
