NVD Description

Note: Versions mentioned in the description apply only to the upstream gstreamer1-plugins-bad-free-gtk package and not the gstreamer1-plugins-bad-free-gtk package as distributed by RHEL.

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.
