The remote host is missing updates to the kernel announced in
advisory RHSA-2009:1024.
Security Fixes:
the exit_notify() function in the Linux kernel did not properly reset the
exit signal if a process executed a set user ID (setuid) application before
exiting. This could allow a local, unprivileged user to elevate their
privileges. (CVE-2009-1337, Important)
the Linux kernel implementation of the Network File System (NFS) did not
properly initialize the file name limit in the nfs_server data structure.
This flaw could possibly lead to a denial of service on a client mounting
an NFS share. (CVE-2009-1336, Moderate)

Users should install this update, which resolves these issues and adds
these enhancements.
