Name of the Vulnerable Software and Affected Versions GStreamer versions prior to 1.18.4

Description The issue is related to a buffer overflow in the GStreamer multimedia framework, which can be exploited by a remote attacker using a malformed Matroska file. This exploitation can lead to unauthorized access to confidential data, disruption of data integrity, and denial of service. The problem arises when parsing certain malformed Matroska files, potentially causing heap corruption.

Recommendations For versions prior to 1.18.4, update to version 1.18.4 or later to resolve the issue. As a temporary workaround, consider restricting the use of malformed Matroska files until a patch is applied. Avoid using the vulnerable GStreamer function when parsing Matroska files until the issue is resolved.
