gstreamer1-plugins-bad-free: gstreamer: rfbsrc/librfb Hextile heap out-of-bounds write with 16bpp framebuffer

A heap buffer overflow vulnerability was found in GStreamer's rfbsrc plugin. When a client connects to a malicious RFB/VNC server that advertises a 16bpp framebuffer and sends Hextile-encoded updates, the Hextile background fill path writes 32-bit pixel values into a buffer allocated for 16-bit...

CVE-2026-52717

A memory corruption vulnerability was found in GStreamer's gst-libav plugin. The gstffmpegpipeclose function incorrectly calls gfree on a pointer to an embedded struct member that was never heap-allocated. A remote attacker could trick a user into opening a specially crafted media file, causing t...

gstreamer1-plugins-good: gstreamer: out-of-bounds read in avidemux vprp video field descriptor parsing

A flaw was found in GStreamer gst-plugins-good avidemux. In gstavidemuxriffparsevprp, the number of available gstriffvprpvideofielddesc entries is calculated by dividing the remaining buffer size by the attacker-controlled vprp-fields value, rather than by sizeofgstriffvprpvideofielddesc. This ca...
