ssh-vulnkey overlooks keys which have options in authorized_keys

Great, I am happy that it has also been fixed.

However, this the second time that this duplication happened to me and
I DID check before posting whether there was anything already reported
about the problem. I used launchpad search facility to find related
reports and nothing came up.  Now I am wondering why, is there a delay,
am I doing something wrong?

[Bug 230344] [NEW] bug in ssh-vulnkey - ref USN-612-2

2008-05-14 Thread Peter Dobcsanyi
*** This bug is a security vulnerability ***

Public security bug reported:

Binary package hint: openssh-blacklist

The ssh-vulnkey program doesn't correctly parse authorized_keys
files resulting in missing compromised keys. This bug manifests itself
when the option field has parameters containing space. Some options,
most importantly command, can contain space in quoted strings.

Here is an example showing two lines of an authorized_keys file
with the same compromised key:

command=hg-ssh 
~/repos/ddb,no-port-forwarding,no-X11-forwarding,no-agent-forwarding ssh-rsa 
B3NzaC1yc2EBIwAA...
no-port-forwarding,no-X11-forwarding,no-agent-forwarding ssh-rsa 
B3NzaC1yc2EBIwAA...

Only the second line reported as compromised.

The option field is frequently used to (fine) control access to sshd
hosts, so this bug seriously undermines the usefulness of ssh-vulnkey.
