Debian Security Advisory DSA-4733-1 [email protected]

Package : qemu
CVE ID : CVE-2020-8608
Debian Bug : 964793

It was discovered that incorrect memory handling in the SLIRP networking
implementation could result in denial of service or potentially the
execution of arbitrary code.

For the stable distribution (buster), this problem has been fixed in
version 1:3.1+dfsg-8+deb10u7. In addition this update fixes a regression
caused by the patch for CVE-2020-13754, which could lead to startup
failures in some Xen setups.

We recommend that you upgrade your qemu packages.

For the detailed security status of qemu please refer to
its security tracker page at:
https://security-tracker.debian.org/tracker/qemu
