Patch 007: sysctl

Contributed by jose on from the invalid-arguments dept.

The OpenBSD team has released Patch 007 for all architectures using the 3.4 release. As described on the errata entry , "It is possible for a local user to cause a crash via sysctl(3) with certain arguments." This is a local denial of service which is remedied by this patch.

For OpenBSD-3.3, Patch 012 has been released to address this issue.

    Is this the same problem which is described here for netbsd?

      I don't think so. The NetBSD problems were located in sys/kern/kern_sysctl.c while patch 007 makes some changes to sys/uvm/uvm_glue.c

      Code to crash OpenBSD using this bug was sent to the full-disclosure mailing list in a fake email .
