This vulnerability allows remote attackers to execute arbitrary code on vulnerable installations of VLC.

User interaction is required to exploit this vulnerability in that the target must visit a malicious page or open a malicious file.

An heap memory corruption occured when VLC parsed an malformed MPEG-4 file that contain an invalid Sample Table and Sample Description (STSD) Atoms size. An attacker can leverage this vulnerability to execute arbitrary code under the context of the current process.
