GStreamer FLAC File Parsing Integer Overflow Remote Code Execution
Vulnerability. This vulnerability allows remote attackers to execute
arbitrary code on affected installations of GStreamer. Interaction with
this library is required to exploit this vulnerability but attack vectors
may vary depending on the implementation. The specific flaw exists within
the parsing of FLAC audio files. The issue results from the lack of proper
validation of user-supplied data, which can result in an integer overflow
before allocating a buffer. An attacker can leverage this vulnerability to
execute code in the context of the current process. Was ZDI-CAN-20775.
