Description Andrej Nemec 2016-07-15 06:45:17 UTC 
A vulnerability was found in ecryptfs-setup-swap script that is provided by the upstream ecryptfs-utils project.

On systems using systemd 211 or newer and GPT partitioning, the unencrypted swap partition was being automatically activated during boot and the encrypted swap was not used. This was due to ecryptfs-setup-swap not marking the swap partition as "no-auto", as defined by the Discoverable Partitions Spec.
