CVE-2026-59691

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...

gstreamer1-plugins-bad-free: GStreamer: Out-of-bounds read via JPEG segment length validation in VA decoder

An out-of-bounds read vulnerability was found in the VA JPEG decoder in GStreamer's gst-plugins-bad. The JPEG parser reads a segment length value from the bitstream without validating it against available data. A remote attacker could trick a user into opening a specially crafted JPEG file, causi...

gstreamer1-plugins-bad-free: GStreamer: Signed integer overflow in VMnc decoder cursor payload handling

A signed integer overflow vulnerability was found in GStreamer's VMnc decoder. A crafted VMnc stream with large cursor dimensions can overflow signed integer payload-size arithmetic, bypassing a length check and leading to out-of-bounds reads. A remote attacker could trick a user into opening a...

gstreamer1-plugins-bad-free: GStreamer: Heap buffer overflow via crafted VNC server rectangle in librfb

A heap buffer overflow vulnerability was found in GStreamer's librfb RFB/VNC client. The rectangle bounds check incorrectly validates area rather than individual dimensions, allowing a malicious VNC server to send a rectangle that extends beyond the framebuffer. A remote attacker could set up a...

gstreamer1-plugins-good: GStreamer: Heap buffer overflow in WavPack decoder via integer overflow

A flaw was found in GStreamer's WavPack audio decoder in gst-plugins-good. When processing a specially crafted WavPack file, an integer overflow in the buffer size calculation 4 blocksamples channels in gstwavpackdechandleframe causes a very small heap allocation. The WavPack library then writes...

gstreamer1-plugins-bad-free: GStreamer: Denial of service via AV1 tile_list_obu parser byte/bit confusion

A denial of service vulnerability was found in GStreamer's AV1 codec parser in gst-plugins-bad. The gstav1parserparsetilelistobu function passes a byte count to a bit-reader API that expects a bit count, causing parser desynchronization. A remote attacker could trick a user into opening a special...
