qemu vulnerabilities
A security issue affects these releases of Ubuntu and its derivatives:
Several security issues were fixed in QEMU.
Software Description
Felipe Franciosi, Raphael Norwitz, and Peter Turschmid discovered that QEMU incorrectly handled iSCSI server responses. A remote attacker in control of the iSCSI server could use this issue to cause QEMU to crash, leading to a denial of service, or possibly execute arbitrary code. (CVE-2020-1711)
It was discovered that the QEMU libslirp component incorrectly handled memory. A remote attacker could use this issue to cause QEMU to crash, resulting in a denial of service, or possibly execute arbitrary code. (CVE-2020-7039, CVE-2020-8608)
