How to update for the Heartbleed fix

Hello

i found out that one of my servers uses OpenSSL 1.0.1e on Debian 7.4.

I tried to "apt-get update && apt-get upgrade" but there is no sign of any libssl nor openssl update. Do i have to get the source and compile it by myself?

EDIT: here is my apt/source.list AND apt-cache policy openssl

$ cat /etc/apt/sources.list #

#deb cdrom:[Debian GNU/Linux 6.0.1a _wheezy_ - Official amd64 NETINST Binary-1 20110320-15:00]/ squeeze main
#deb cdrom:[Debian GNU/Linux 6.0.1a _wheezy_ - Official amd64 NETINST Binary-1 20110320-15:00]/ squeeze main

apt-cache policy openssl:

openssl:

Installed: 1.0.1e-2+deb7u4

Candidate: 1.0.1e-2+deb7u4

Version table:

*** 1.0.1e-2+deb7u4 0

EDIT - HERE IS THE FIX

I added this repo and everything works as it should now:
