CVE-2026-59691 (GCVE-0-2026-59691)

Vulnerability from cvelistv5 – Published: 2026-07-09 09:34 – Updated: 2026-09-10 14:43

Title

Gstreamer1-plugins-bad-free: gstreamer: rfbsrc/librfb hextile heap out-of-bounds write with 16bpp framebuffer

Summary

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 pixels. This type mismatch causes an out-of-bounds heap write that can lead to denial of service (process crash) and potential memory corruption.

Severity

7.1 (High)

CVE-2026-59692 (GCVE-0-2026-59692)

Vulnerability from cvelistv5 – Published: 2026-07-09 09:35 – Updated: 2026-09-10 14:43

Title

Gstreamer1-plugins-bad-free: gstreamer: dtls certificate subject dn stack buffer overflow in openssl_verify_callback

Summary

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 oversized Subject DN that exceeds the buffer, causing a stack buffer overflow and process crash, resulting in denial of service.

Severity

7.5 (High)

Restrict network access to WebRTC/DTLS endpoints to trusted peers only via firewall rules.\n3.

Detection rules are retrieved from Rulezet.

The MITRE ATT&CK techniques below are AI-generated suggestions, inferred from the description of the vulnerability by the CIRCL/vulnerability-attack-technique-classification-roberta-base model, served locally by ML-Gateway. They have not been verified by an analyst and are provided for guidance only.
The approach is described in our paper Mapping CVEs to MITRE ATT&CK Techniques: A Curated Gold-Set Classifier and the Limits of LLM-Assisted Label Expansion.
