CVE ID:	CVE-2010-0727
Description:	The gfs2_lock function in the Linux kernel before 2.6.34-rc1-next-20100312, and the gfs_lock function in the Linux kernel on Red Hat Enterprise Linux (RHEL) 5 and 6, does not properly remove POSIX locks on files that are setgid without group-execute permission, which allows local users to cause a denial of service (BUG and system crash) by locking a file on a (1) GFS or (2) GFS2 filesystem, and then changing this file's permissions.
Test IDs:	1.3.6.1.4.1.25623.1.0.71934   1.3.6.1.4.1.25623.1.0.67169   1.3.6.1.4.1.25623.1.0.67406   1.3.6.1.4.1.25623.1.0.67165   1.3.6.1.4.1.25623.1.0.67170   1.3.6.1.4.1.25623.1.0.122375
