USN-4405-1: GLib Networking vulnerability

29 June 2020

Fraudulent security certificates could allow sensitive information to be exposed when accessing the Internet.




It was discovered that glib-networking skipped hostname certificate
verification if the application failed to specify the server
identity. A remote attacker could use this to perform a
person-in-the-middle attack and expose sensitive information.

Update instructions

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

Ubuntu 20.04
Ubuntu 19.10
Ubuntu 18.04
Ubuntu 16.04

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