The remote Oracle Linux host is missing one or more security updates.
Description of changes:
* CVE-2012-0879: Denial of service in CLONE_IO.
CLONE_IO reference counting error could be exploited by an
unprivileged local user to cause denial of service.
* CVE-2012-1097: NULL pointer dereference in the ptrace subsystem.
Under certain circumstances, ptrace-ing a process could lead to a NULL
pointer dereference and kernel panic.
* CVE-2012-1090: Denial of service in the CIFS filesystem reference
Under certain circumstances, the CIFS filesystem would open a file on
lookup. If the file was determined later to be a FIFO or any other
special file the file handle would be leaked, leading to reference
counting mismatch and a kernel OOPS on unmount.
An unprivileged local user could use this flaw to crash the system.

- cifs: fix dentry refcount leak when opening a FIFO on lookup (Jeff Layton)
- block: Fix io_context leak after failure of clone with CLONE_IO (Louis
