NVD Description

Note: Versions mentioned in the description apply only to the upstream gstreamer-plugins-bad-free-devel package and not the gstreamer-plugins-bad-free-devel package as distributed by RHEL. See How to fix? for RHEL:7 relevant fixed versions and status.

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.
