libvncserver: Improper input sanitization in rfbProcessClientNormalMessage in rfbserver.c

An issue was discovered in LibVNCServer through 0.9.11. rfbProcessClientNormalMessage in rfbserver.c does not sanitize msg.cct.length, leading to access to uninitialized and potentially sensitive data or possibly unspecified other impact e.g., an integer overflow via specially crafted VNC packets...

Qemu: memory exhaustion through framebuffer update request message in VNC server

VNC server implementation in Quick Emulator QEMU was found to be vulnerable to an unbounded memory allocation issue, as it did not throttle the framebuffer updates sent to its client. If the client did not consume these updates, VNC server allocates growing memory to hold onto this data. A...
