CVE-2014-0249 sssd: incorrect expansion of group membership when encountering a non-POSIX group
It was reported [1] that SSSD improperly expanded group membership when it encountered a non-POSIX group in the group membership chain. For instance:
user -> posix_group1 -> non_posix_group -> posix_group2
With the group memberships noted above, SSSD should include the user as a member of both posix_group1 and posix_group2, however due to the position of the non-POSIX group, SSSD halts processing at it and never reaches posix_group2, leaving the user as a member of posix_group1 and not posix_group2.
SSSD has the capability to set a 'deny' ACL for both users and groups, so in a situation like that illustrated above, if posix_group2 was present in a 'deny' ACL, the user would be granted access
