CVE-2021-3185

CVSS v2.0

10

Critical

VectorAV:N/AC:L/Au:N/C:C/I:C/A:C
Name of the Vulnerable Software and Affected Versions gst-plugins-bad versions prior to 1.18.1
Description A flaw was found in the gstreamer h264 component where when parsing a h264 header, an attacker could cause the stack to be smashed, memory corruption and possibly code execution. The vulnerability is related to the gst h264 slice parse dec ref pic marking function and is associated with a buffer overflow in memory, which could allow a remote attacker to execute arbitrary code or cause a denial of service.
Recommendations For versions prior to 1.18.1, update to version 1.18.1 or later to resolve the issue. As a temporary workaround, consider disabling the gst h264 slice parse dec ref pic marking function until a patch is available. Restrict access to the gstreamer h264 component to minimize the risk of exploitation.
