Ubuntu 16.04 LTS / 18.04 LTS / 20.04 LTS : p11-kit vulnerabilities (USN-4677-1)

medium Nessus Plugin ID 144747

Language:

Synopsis

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

Description

The remote Ubuntu 16.04 LTS / 18.04 LTS / 20.04 LTS host has packages installed that are affected by multiple vulnerabilities as referenced in the USN-4677-1 advisory.

 David Cook discovered that p11-kit incorrectly handled certain memory operations. An attacker could use this issue to cause p11-kit to crash, resulting in a denial of service, or possibly execute arbitrary code.

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.
