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.

Solution(s)

  • redhat-upgrade-gfs-kernel
  • redhat-upgrade-gfs-kernel-hugemem
  • redhat-upgrade-gfs-kernel-largesmp
  • redhat-upgrade-gfs-kernel-smp
  • redhat-upgrade-gfs-kernel-xenu
  • redhat-upgrade-gfs-kernheaders

With Rapid7 live dashboards, I have a clear view of all the assets on my network, which ones can be exploited, and what I need to do in order to reduce the risk in my environment in real-time. No other tool gives us that kind of value and insight.
