high Nessus Plugin ID 128031

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-4105-1 advisory.

 StephanZeisbergdiscovered that the CUPS SNMP backend incorrectly handled encoded ASN.1 inputs. A remote attacker could possibly use this issue to cause CUPS to crash by providing specially crafted network traffic. (CVE-2019-8696, CVE-2019-8675)

 It was discovered that CUPS did not properly handle client disconnection events. A local attacker could possibly use this issue to cause a denial of service or disclose memory from the CUPS server.

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 packages.
