Hello,A heap buffer overflow issue was found in the SLiRP networking implementation of the QEMU emulator. It occurs in tcp_emu() routine while emulating Identification protocol and copying message data to a socket buffer.
A user/process could use this flaw to crash the Qemu process on the host resulting in DoS or potentially execute arbitrary code with privileges of the QEMU process.
