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
An advisory has been issued which should help the problem
described in this bug report. This report is therefore being
closed with a resolution of ERRATA. For more information
