CVE-2026-121259
Gst-plugins-bad: gst-plugins-bad: integer overflows and division by zero in jpeg 2000 decimator
A flaw was found in the GStreamer JPEG 2000 decimator in gst-plugins-bad. Crafted JPEG 2000 media can cause integer overflows or division by zero during tile processing. An application that processes the malicious media may crash, resulting in a denial of service.
Fixes and workarounds
Workaround
Applications that do not require JPEG 2000 decimation can avoid using the jp2kdecimator element and reject untrusted JPEG 2000 media before it reaches a pipeline that uses this element.
