Amazon Linux AMI Security Advisory: ALAS-2012-47
Advisory Release Date: 2014-09-14 15:22 Pacific
A heap-based buffer overflow flaw was found in the way the libvorbis library parsed Ogg Vorbis media files. 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 )
Run yum update libvorbis to update your system.
