gstreamer: gstreamer: DTLS certificate Subject DN stack buffer overflow in openssl_verify_callback

A stack buffer overflow vulnerability was found in GStreamer's DTLS plugin. During a DTLS handshake, the peer certificate Subject Distinguished Name is printed into a fixed-size 2048-byte stack buffer without bounds checking. A remote unauthenticated attacker can send a certificate with an...

gstreamer: 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-2026-73434

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...
