Description Marcel Holtmann 2006-03-21 08:14:41 EST
+++ This bug was initially created as a clone of Bug #186057 +++

Interesting behaviour of some Linux kernels that may be exploited by a remote
attacker to abuse the ID field of IP packets, effectively bypassing the zero IP
ID in DF packets countermeasure implemented since 2.4.8 (IIRC).

A fix for this problem has just been committed to the RHEL3 U8
patch pool this evening (in kernel version 2.4.21-40.5.EL).

Adding a couple dozen bugs to CanFix list so I can complete the stupid advisory.
