U radu programskog paketa vlc uočena je nova sigurnosna ranjivost. Radi se o alatu za reprodukciju audio i video sadržaja različitih formata. Uočena ranjivost posljedica je prepisivanja međuspremnika stoga koje se javlja u programskom dodatku vezanom uz MP4 dekoder. Napadači mogu iskoristiti ovu ranjivost za pokretanje proizvoljnog programskog koda pod uvjetom da uspiju natjerati žrtvu na otvaranje posebno oblikovanih MP4 datoteka. Svim se korisnicima savjetuje nadogradnja ranjivih paketa kako bi opisanu ranjivost otklonili.

Package        : vlc
Vulnerability  : heap-based buffer overflow
Problem type   : local
Debian-specific: no
CVE ID         : none yet

Aliz Hammond discovered that the MP4 decoder plugin of vlc, a multimedia
player and streamer, is vulnerable to a heap-based buffer overflow.
This has been introduced by a wrong data type being used for a size
calculation.  An attacker could use this flaw to trick a victim into
opening a specially crafted MP4 file and possibly execute arbitrary code
or crash the media player.


The oldstable distribution (lenny) is not affected by this problem.

For the stable distribution (squeeze), this problem has been fixed in
version 1.1.3-1squeeze5.

For the testing distribution (wheezy), this problem will be fixed soon.

For the unstable distribution (sid), this problem has been fixed in
version 1.1.8-3.


We recommend that you upgrade your vlc packages.
