[USN-8205-1] GStreamer Bad Plugins vulnerabilities
==========================================================================
Ubuntu Security Notice USN-8205-1
April 23, 2026
gst-plugins-bad1.0 vulnerabilities
==========================================================================
A security issue affects these releases of Ubuntu and its derivatives:
- Ubuntu 18.04 LTS
- Ubuntu 16.04 LTS
Summary:
Several security issues were fixed in GStreamer Bad Plugins.
Software Description:
- gst-plugins-bad1.0: GStreamer plugins
Details:
It was discovered that multiple plugins in GStreamer contained arithmetic
overflows. An attacker could possibly use this issue to cause applications
using the plugins to crash, resulting in a denial of service, or possibly
execute arbitrary code. (CVE-2023-37329, CVE-2023-40474, CVE-2023-40475,
CVE-2023-40476)
It was discovered that the MXF demuxer plugin in GStreamer did not
properly manage memory. An attacker could possibly use this issue to cause
applications using the plugin to crash, resulting in a denial of service,
or possibly execute arbitrary code. (CVE-2023-44446)
It was discovered that the H265 codec plugin in GStreamer could be made
to write out of bounds. An attacker could possibly use this issue to
cause applications using the plugin to crash, resulting in a denial of
service, or possibly execute arbitrary code. (CVE-2025-3887)
Update instructions:
The problem can be corrected by updating your system to the following
package versions:
Ubuntu 18.04 LTS
gstreamer1.0-plugins-bad 1.14.5-0ubuntu1~18.04.1+esm1
Available with Ubuntu Pro
libgstreamer-plugins-bad1.0-0 1.14.5-0ubuntu1~18.04.1+esm1
Available with Ubuntu Pro
Ubuntu 16.04 LTS
gstreamer1.0-plugins-bad 1.8.3-1ubuntu0.2+esm1
Available with Ubuntu Pro
libgstreamer-plugins-bad1.0-0 1.8.3-1ubuntu0.2+esm1
Available with Ubuntu Pro
In general, a standard system update will make all the necessary changes.

Update instructions:
The problem can be corrected by updating your system to the following
package versions:
Ubuntu 22.04 LTS
linux-image-5.15.0-1099-ibm 5.15.0-1099.102
linux-image-ibm 5.15.0.1099.95

linux-image-ibm-5.15 5.15.0.1099.102~20.04.1
Available with Ubuntu Pro
After a standard system update you need to reboot your computer to make
all the necessary changes.
ATTENTION: Due to an unavoidable ABI change the kernel updates have
been given a new version number, which requires you to recompile and
reinstall all third party kernel modules you might have installed.
Unless you manually uninstalled the standard kernel metapackages
(e.g. linux-generic, linux-generic-lts-RELEASE, linux-virtual,
linux-powerpc), a standard system upgrade will automatically perform
this as well.
