high Nessus Plugin ID 186613

Language:

Synopsis

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

Description

The remote Ubuntu 16.04 ESM / 18.04 ESM host has packages installed that are affected by multiple vulnerabilities as referenced in the USN-6463-2 advisory.

 USN-6463-1 fixed vulnerabilities in Open VM Tools. This update provides the corresponding updates for Ubuntu 16.04 LTS and Ubuntu 18.04 LTS.

 Original advisory details:

 It was discovered that Open VM Tools incorrectly handled SAML tokens. A

 remote attacker with Guest Operations privileges could possibly use this

 issue to elevate their privileges. (CVE-2023-34058)

 Matthias Gerstner discovered that Open VM Tools incorrectly handled file

 descriptors when dropping privileges. A local attacker could possibly use

 this issue to hijack /dev/uinput and simulate user inputs. (CVE-2023-34059)

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

Update the affected open-vm-tools, open-vm-tools-desktop and / or open-vm-tools-dev packages.
