===================================================
Description

The eCryptfs subsystem in the Linux kernel before 3.18 allows local users to gain privileges via a large filesystem stack that includes an overlayfs layer, related to fs/ecryptfs/main.c and fs/overlayfs/super.c.

Not sure, if SUSE supports 3.x kernel branch. If no, please, close report as invalid.
Comment 1 Marcus Meissner 2017-04-04 17:43:12 UTC
We do support also 2.6 kernels.

I remember a similar bug though.

patches.suse/ovl09-fs-limit-filesystem-stacking-depth.patch in SLE12/SLE12-SP1 trees.

overlayfs is not supported in older kernels though
Comment 2 Marcus Meissner 2017-04-18 16:06:04 UTC
as we did not have overlayfs on SLE11, only ecryptfs would have been stackable (?)
and so this would not be an issue.
Comment 3 Jeff Mahoney 2017-06-22 19:50:09 UTC
I'm not sure this is actually an issue in SLE11 since we don't allow users to mount arbitrary file systems outside of the GNOME interface.  In any case, it's a trivial fix so I've pushed it for SLE11 SP4.  Newer releases are unaffected as they have always contained this patch.
