A remote user can create a specially crafted FreeType font that, when loaded by the target user, will execute arbitrary code on the target user's system [CVE-2011-3439].
A remote user can create specially crafted HTML that, when loaded by the target user, will cause libinfo to disclose potentially sensitive information via DNS name lookups [CVE-2011-3441]. Erling Ellingsen of Facebook and Per Johansson of Blocket AB reported this vulnerability.
