Description Mark J. Cox 2005-11-24 11:31:16 UTC

+++ This bug was initially created as a clone of Bug #174081 +++

A typo in IPv6 flowlabel handling code in Linux kernels 2.4 up
        to 2.4.32 and 2.6 before 2.6.14 could be used by a local
        attacker to cause the kernel free non-allocated memory and in
        turn corrupt kernel memory and/or crash the machine.

Fixed upstream by:
http://linux.bkbits.net:8080/linux-2.6/cset@435ebd2095VXAPIHGRQXkibspCvlPw

This issue affects kernels 2.4 as well as 2.6 up to 2.6.14
