Notes

[etch] - openssh <no-dsa> (minor issue in weak security measure)
[sarge] - openssh <no-dsa> (minor issue in weak security measure)
An exploit needs limited control over the machine running a
trusted X client, so this is only a slight privilege
escalation. The X Security extension is merely an afterthought
and is unlikely to provide strong security guarantees.
