Package: libssl1.0.0
Version: 1.0.1e-2+deb7u5
Severity: grave
Tags: security
Justification: user security hole

Dear Maintainer,
when I did "apt-get update&&apt-get upgrade" today to get a fix for CVE-2014-0160, I got this from apt:

Setting up libssl1.0.0:amd64 (1.0.1e-2+deb7u5) ...
Setting up libssl-dev (1.0.1e-2+deb7u5) ...
Setting up openssh-client (1:6.0p1-4+deb7u1) ...
Setting up openssh-server (1:6.0p1-4+deb7u1) ...
[ ok ] Restarting OpenBSD Secure Shell server: sshd.
Setting up a2ps (1:4.14-1.1+deb7u1) ...
Setting up libxalan2-java (2.7.1-7+deb7u1) ...
Setting up openssl (1.0.1e-2+deb7u5) ...

It restarted OpenSSH... and only OpenSSH. I then ran this command:

So, uh, looks like although the fixed library is on my system, all the interesting and
maybe-affected services (like couchdb, stunnel, lighttpd, postfix, ...) are still
vulnerable until I reboot my server, which is not exactly standard procedure after
installing updates?
