I've already moaned. The correct answer is:
Prior to 2.0.31 and earlier are vulnerable to teardrop
2.0.32 and above are not.
RedHat 5.0 ships with a 2.0.31+patches that is not vulnerable. RH5.0
update for the 2.0.32 kernel is on ftp.redhat.com
update kernel and/or apply the patch to the existing kernel if you wish
to remain running an older kernel for reasons such as compliance testing.
I _hope_ someone in RH or Cert merely got teardrop and land muddled up.
