Description Martin Prpič 2015-10-30 13:52:16 UTC 
An out-of-bounds memory access flaw was found in the way libxml2 parsed documents with an unclosed comment. An attacker could provide specially crafted input that, when parsed by an application using libxml2, could cause that application to disclose arbitrary parts of that application's memory, potentially revealing sensitive information.
