medium Nessus Plugin ID 133796

Language:

Synopsis

The remote Ubuntu host is missing one or more security updates.

Description

The remote Ubuntu 16.04 LTS / 18.04 LTS host has packages installed that are affected by multiple vulnerabilities as referenced in the USN-4283-1 advisory.

 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)

Tenable has extracted the preceding description block directly from the Ubuntu security advisory.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

Solution
