CVE-2017-15124
HIGHQEMU < 2.11.0 - Denial of Service via Unbounded VNC Framebuffer Updates
Title source: llmDescription
VNC server implementation in Quick Emulator (QEMU) 2.11.0 and older 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 malicious remote VNC client could use this flaw to cause DoS to the server host.
