CVE-2023-44429: GStreamer AV1 Codec Parsing Heap-based Buffer Overflow Remote Code Execution Vulnerability
[AV1 codec parser buffer overflow]
Other sources
GStreamer AV1 Codec 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 AV1 encoded video files. The issue results from the lack of proper validation of the length of user-supplied data prior to copying it to a fixed-length heap-based buffer. An attacker can leverage this vulnerability to execute code in the context of the current process. Was ZDI-CAN-22226.
— MITRE
Heap-based buffer overflow in the AV1 codec parser when handling certain malformed streams before GStreamer 1.22.7. It is possible for a malicious third party to trigger a crash in the application, and possibly also effect code execution through heap manipulation.
