CVE-2023-37328

GStreamer PGS File Parsing Heap-based Buffer 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 PGS subtitle files. The issue results from the lack of
proper validation of the length of user-supplied data prior to copying it
to a heap-based buffer. An attacker can leverage this vulnerability to
execute code in the context of the current process. Was ZDI-CAN-20994.
