Description Stefan Behte (RETIRED) gentoo-dev Security 2009-07-10 22:58:54 UTC 
CVE-2009-1388 (http://nvd.nist.gov/nvd.cfm?cvename=CVE-2009-1388):
  The ptrace_start function in kernel/ptrace.c in the Linux kernel
  2.6.18 does not properly handle simultaneous execution of the
  do_coredump function, which allows local users to cause a denial of
  service (deadlock) via vectors involving the ptrace system call and a
  coredumping thread.
Comment 1 Robert Buchholz (RETIRED) gentoo-dev 2009-07-13 13:39:25 UTC 
probably affects all 2.6.18 based kernels, not just the .18 base
