Description Mark J. Cox 2005-03-16 11:10:24 UTC 
See #151240 for POC and patch

+++ This bug was initially created as a clone of Bug #151240 +++

Ben Martel and Stephen Blackheath discovered a DoS attack that a client of pppd
can make that can hang the server machine.  The bug is in the Linux kernel 2.6
(tested on 2.6.9), but it looks like it also exists in the 2.4 series.

A fix for this problem has been committed to the RHEL21 source pool for kernel
