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. Fix in 2.6.33 onwards, https://github.com/torvalds/linux/commit/86acdca1b63e6890540fa19495cfc708beff3d8b |
