Description Alexandros Toptsoglou 2020-02-06 14:47:39 UTC
CVE-2020-8608

A out-of-bounds heap buffer access issue was found in the SLiRP networking implementation
of the QEMU emulator. It occurs in tcp_emu() routine while emulating IRC and
other protocols due to unsafe usage of snprintf(3) function.

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 on the host.
