Description Andrej Nemec 2016-11-23 08:48:00 UTC 
The vulnerability exists due to the library’s failure to check if certain message types support a particular flag. When this flag is set, the library will cast the structure to an alternative structure and then assign to fields that aren’t supported by the message type. Due to the message type not being able to support this flag, the library will write outside the bounds of the heap buffer. This can lead to code execution under the context of the library.
