VUL-0: CVE-2020-8608: kvm,qemu: potential OOB access due to unsafe snprintf() usages
Last modified: 2022-06-10 09:34:25 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.
