Description Kamil Dudka 2017-05-17 11:07:30 EDT

+++ This bug was initially created as a clone of Bug #1451801 +++

Description of problem:

When using "setfacl --restore <aclfile>" command, the command may fail when setting ACLs because of the reading of unitialized memory, causing unexpected code path to be executed.

Requesting backport of http://git.savannah.gnu.org/cgit/acl.git/commit?id=33f01b5d

Version-Release number of selected component (if applicable):

acl-2.2.49-7.el6.x86_64

How reproducible:

Always on customer setup, never on mine.

Additional info:

Backporting http://git.savannah.gnu.org/cgit/acl.git/commit?id=33f01b5d fixed the issue.

--- Additional comment from Kamil Dudka on 2017-05-17 16:59:31 CEST ---

As discussed privately, this is easy and safe to backport.  Moreover, the fix is already verified in customer's environment.
