It is possible for a local user to cause a system panic by flooding it with spoofed ARP

requests.

Since this same bug resulted in a root compromise in the wu-ftpd ftp server

it is possible that this bug may allow an attacker to gain escalated privileges

on OpenBSD.

All architectures

<a href="http://man.openbsd.org/?query=httpd&sektion=8">httpd(8)</a> leaks file inode numbers via ETag header as well as child PIDs in multipart MIME boundary generation. This could lead, for example, to NFS exploitation because it uses inode numbers as part of the file handle.

<a href="http://man.openbsd.org/?query=ssl&sektion=8">ssl(8)</a> an information leak can occur via timing by performing a MAC computation

On OpenBSD, named runs as a non-root user in a chrooted environment
