high Tenable Self-Hosted Container Security Plugin ID 455387

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

- 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. (CVE-2026-52720)

Solution

Update the gst-plugins-bad1.0 library and its related packages to version 1.26.2-3+deb13u3 or later.
