Releases
Packages
- glib-networking - Network extensions for GLib
Details
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

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