What's this security update KB908519? No mention on microsoft.com!

[Guest]

My windows update just downloaded this security update:

Security Update for Windows XP (KB908519).

The knowledge base contains no references to 908519! What's going on?

Even worse, the explanation says:

A security issue has been identified that could allow an attacker to
compromise your Microsoft Windows-based system and gain control over it. You

Uh, guess what - that link doesn't exist on the site, either.

Should I be worried about the Windows Update channel?

Oh, it's finally showed up on the site now. That was decidedly uncool - to
let loose an update before information about it was posted to microsoft.com.

Anyway, looks like it's important.
