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