Statement: Red Hat Product Security has rated this issue as having Low security impact. This issue is not currently planned to be addressed in future updates. For additional information, refer to the Issue Severity Classification: https://access.redhat.com/security/updates/classification/.
Mitigation: There are several restrictions to successful exploitation of this flaw:
~~~
1. ONLY applications compiled with libuser are affected. The affected code is hit only when a move operation is conducted on user home directory.
2. The attacker needs to have a shell account on the target machine.
3. Since this is a TOCTOU attack, precise timing is requi

CVE-2012-5644 libuser: (Complete) Information disclosure when moving user's home directory
An information disclosure flaw was found in the way libuser, an user and group account administration library, performed movement of user's home directory. Previously, during the move the ownership of all the (sub)entries present in directory tree, to be moved, were changed from privileged user account to the effective user id of the user, the home directory should belong to. A local attacker could use this flaw to conduct hardlink attacks and possibly obtain unauthorized access to arbitrary system file.
This issue was found by Miloslav Trmač of Red Hat.

This issue affects the versions of the libuser package, as shipped with Red Hat Enterprise Linux 5 and 6.

CVE-2012-5630 libuser: TOCTOU race conditions by copying and removing directory trees
A TOCTOU (time-of-check time-of-use) race condition was found in the way libuser, a user and group account administration library, performed copying and removal of (user) directory trees. A local attacker, with permissions to write into particular directory, could use this flaw to conduct symbolic link attacks, leading to their ability to alter / remove directories outside of this directory (tree), if this directory was simultaneously modified (copied or removed) via libuser functionality.
This issue was found by Florian Weimer of Red Hat Product Security Team.
