Description Andrej Nemec 2016-07-15 06:48:45 UTC 
A vulnerability was found in ecryptfs-setup-swap script that is provided by the upstream ecryptfs-utils project.

When GPT swap partitions are located on NVMe or MMC drives, ecryptfs-setup-swap fails to mark these swap partitions as "no-auto".

As a consequence, when using encrypted home directory with an NVMe or MMC drive, the swap is left unencrypted. There's also a usability issue in that users are erroneously prompted to enter a pass-phrase to unlock their swap partition at boot.

This vulnerability exists due to an incomplete fix for CVE-2015-8946
