Description Agostino Sarubbo gentoo-dev 2014-07-06 07:00:52 UTC 
CVE-2014-0203 (http://nvd.nist.gov/nvd.cfm?cvename=CVE-2014-0203):
  The __do_follow_link function in fs/namei.c in the Linux kernel before 
  2.6.33 does not properly handle the last pathname component during use 
  of certain filesystems, which allows local users to cause a denial of service 
  (incorrect free operations and system crash) via an open system call.
