Upgrade OpenSSH in 6.3 and 7.0 RELENG

[Jordi Espasa Clofent]

Hello folks,

I need to upgrade the OpenSSH from the shiped 4.5p1 versions in 6.x and 
7.x branches to 4.5p2 or higher(1).

I've updated the source tree in 6.3 and 7.0 RELENG boxes with a system 
upgrade in mind, but the version is 4.5p1:

# cat /usr/src/crypto/openssh/version.h | grep -i ssh_version_base && 
uname -r
#define SSH_VERSION_BASE        "OpenSSH_4.5p1"
6.3-RELEASE-p1

#cat /usr/src/crypto/openssh/version.h | grep -i ssh_version_base
#define SSH_VERSION_BASE        "OpenSSH_4.5p1"

On the other I see that current vesion in -STABLE is 5.2p1, so upgrade 
to STABLE is an obvious option, but, sincerely, I want to avoid to 
upgrade to -STABLE and I prefer to keep the systems in their current RELENG.

¿How can I upgrade the OpenSSH in the _same_ RELENG? ¿Maybe using the ports?

(1) It seems correct some pam_ldap related issues:
