Just spotted the new advisory from CORE: http://www.securityfocus.com/archive/1/462728/30/0/threaded Not an expert, but FreeBSD's src/sys/kern/uipc_mbuf2.c has the very simular code.

Robert, anyone, could you please check?

Eygene,

Sorry for the delayed response on this -- I've only just returned from Tokyo in the last day and am significantly behind in e-mail from the trip.

According to a source analysis by Jinmei, we are not vulnerable, but I will continue tracking the thread. Apparently this vulnerability involved an issue in the handling of M_EXT, and our implementation of clusters differs significantly from OpenBSD, so it seems likely we are not affected. If we discover any information to the contrary, you can be sure that we will get it fixed and release an advisory!
