HelixPlayer is a media player.
A buffer overflow flaw was found in the way HelixPlayer processed Synchronized Multimedia Integration Language (SMIL) files. It was possible for a malformed SMIL file to execute arbitrary code with the permissions of the user running HelixPlayer. (CVE-2007-3410)
All users of HelixPlayer are advised to upgrade to this updated package, which contains a backported patch and is not vulnerable to this issue.
