Package : systemd
Date : March 16, 2012
Affected: 2011.
_______________________________________________________________________
Problem Description:
A vulnerability has been found and corrected in systemd:
A TOCTOU race condition was found in the way the systemd-logind
login manager of the systemd, a system and service manager for Linux,
performed removal of particular records related with user session upon
user logout. A local attacker could use this flaw to conduct symbolic
link attacks, potentially leading to removal of arbitrary system file
(CVE-2012-1174).
The updated packages have been patched to correct this issue.
