System ID Priority Status Summary Last Updated
Red Hat Product Errata RHSA-2011:1241 normal SHIPPED_LIVE Moderate: ecryptfs-utils security update 2011-08-31 19:40:57 UTC

Description Huzaifa S. Sidhpurwala 2011-08-23 05:20:06 UTC 
When mount.ecrpytfs_private calls set setreuid() it doesn't also set the
effective group id. So when it creates the new version, mtab.tmp, it's
created with the group id of the user running mount.ecryptfs_private.
