  "details" : [ "Use-after-free vulnerability in the sofree function in slirp/socket.c in QEMU (aka Quick Emulator) allows attackers to cause a denial of service (QEMU instance crash) by leveraging failure to properly clear ifq_so from pending packets.", "A use-after-free issue was found in the Slirp networking implementation of the Quick emulator (QEMU). It occurs when a Socket referenced from multiple packets is freed while responding to a message. A user/process could use this flaw to crash the QEMU process on the host resulting in denial of service." ],
