delay / new patchs

[slardeur]

Hello,
I'me using last NSA (1.1.0) to check my servers.
this day : Number of pattern found by NSA 184
=> check update : No update found.

When i use Online Update from my server SLES10SP2
Online update display a lot of patchs that NSA dont propose to install ???

Like : last java from ibm ...

or slesp2-libpng
my version is : 1.2.8-19.15 x86_86
=> a lot of security update that NSA dont check:
19.18, 19.20, 19.22, 19.25 ???

NSA have a delay for include patchs ? incomplete checks list ?
