"The remote Oracle Linux 5 host has packages installed that are affected by a vulnerability as referenced in the
ELSA-2010-0291 advisory.
- 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. (CVE-2010-0727)
Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version
number.");
