CVE-2026-52720 on CTRL-OS 26.05

Aliases: CVE-2026-52720

Packages: gst_all_1.gst-plugins-bad

Status: Plausible

Advisory Information

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 malicious VNC server and trick a user into connecting, resulting in an out-of-bounds heap write that could lead to code execution or a crash.
