Description Thierry Carrez (RETIRED) gentoo-dev 2005-03-08 01:29:56 UTC
There is a validation problem in isakmp_parsewoh(). The exploit may not be able to do something else than a malloc error, or, in the worst case, a racoon crash, and it's not sure this could be done without appropriate credentials.

Koon, I've just commited 0.4-r1 and 0.5-r1 with the changes. Since 0.4 has been in portage for a while, I suggest we target 0.4-r1 for stabalization in the next few days so we can have a stable fixed version.
