Base vector

AV:N/AC:M/Au:N/C:C/I:C/A:C

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

Description The issue is related to the use of memory after it has been freed, which can be exploited by a remote attacker to access confidential data, compromise data integrity, and cause a denial of service using a malformed Matroska file. This can occur when demuxing certain malformed Matroska files, potentially leading to unauthorized access and system disruption.

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 to minimize the risk of exploitation.
