OpenBSD and NetBSD are prone to a denial-of-service vulnerability because they fail to properly parse format strings to the 'printf(1)' function.

An attacker can exploit this issue to cause applications using the vulnerable call to crash with a segmentation fault, denying service to legitimate users.

The following are reported vulnerable:

OpenBSD 4.6
NetBSD 5.0.1
