Details
David Benjamin discovered that OpenSSL incorrectly handled comparing
certificates containing a EDIPartyName name type. A remote attacker could
possibly use this issue to cause OpenSSL to crash, resulting in a denial of
service.
Update instructions
The problem can be corrected by updating your system to the following package versions:
Ubuntu 20.10

After a standard system update you need to reboot your computer to make all
the necessary changes.
