USN-4677-1: p11-kit vulnerabilities

5 January 2021

Several security issues were fixed in p11-kit.




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.

Update instructions

The problem can be corrected by updating your system to the following package versions:

Ubuntu 20.10
Ubuntu 20.04
Ubuntu 18.04
Ubuntu 16.04

In general, a standard system update will make all the necessary changes.
