What is CVE-2021-3497?

The GStreamer multimedia framework, prior to version 1.18.4, contains a memory handling vulnerability that occurs when the system processes malformed Matroska files. Specifically, the vulnerability stems from the potential access to memory that has already been freed in certain error code paths during the demuxing process. This can lead to unpredictable behavior, including application crashes or the execution of arbitrary code, particularly when handling maliciously crafted media files.
