Synopsis :

The remote Ubuntu host is missing a security-related patch.

Description :

Ansgar Burchardt discovered that APT incorrectly handled InRelease
files. If a remote attacker were able to perform a man-in-the-middle
attack, this flaw could potentially be used to install altered

This update corrects the issue by disabling InRelease file support
completely. Please note that this update breaks third-party
repositories that provide only a InRelease file and no separate
Release and Release.gpg files. The default Ubuntu repositories do not
use InRelease files.

Solution :

Update the affected apt package.

Medium / CVSS Base Score : 4.3
