Comment 1 Mark J. Cox 2006-01-11 10:25:32 UTC 
NOTE: We have not verified if this issue affects RHEL3.

+++ This bug was initially created as a clone of Bug #177496 +++

A netlink message with nlmsg_len set to 0 can cause an infinite loop holding the
netlink semaphore therefore allowing a local unprivileged DoS.

Here is the upstream fix for this issue:

RHEL3 is not affected, the bug was introduced in a cleanup that never made it
into RHEL3.
