CyberRota Analysis
AI-GeneratedA heap buffer overflow vulnerability exists in the GStreamer rfbsrc plugin, which can be exploited when a client connects to a malicious RFB/VNC server that improperly advertises a 16bpp framebuffer. This flaw allows for out-of-bounds writes, potentially resulting in denial of service through process crashes and memory corruption. Organizations using GStreamer, particularly those relying on remote desktop functionalities, should prioritize patching this vulnerability to mitigate associated risks.
Original NVD Description
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.
