Debian Security Advisory 1576-2 - Matt Zimmerman discovered that entries in ~/.ssh/authorized_keys with options (such as "no-port-forwarding" or forced commands) were ignored by the new ssh-vulnkey tool introduced in openssh 1:4.3p2-9etch1 (see DSA 1576-1). This could cause some compromised keys not to be listed in ssh-vulnkey's output.
