CVE-2020-12829

An integer overflow in the sm501 display device may result in denial of service.

CVE-2020-14364

An out-of-bounds write in the USB emulation code may result in guest-to-host code execution.

CVE-2020-15863

A buffer overflow in the XGMAC network device may result in denial of service or the execution of arbitrary code.

CVE-2020-16092

A triggerable assert in the e1000e and vmxnet3 devices may result in denial of service.

For the stable distribution (buster), these problems have been fixed in version 1:3.1+dfsg-8+deb10u8.

We recommend that you upgrade your qemu packages.

For the detailed security status of qemu please refer to its security tracker page at: [link moved to references]");
