      Apple Issues Patch to Address Screen Saver Bypassing
    ------------------------------------------------------------------------

    SUMMARY

    As we reported in our previous article:
    <http://www.securiteam.com/unixfocus/5JP051PAKI.html> MacOS X's
    Screensaver Can Be Crashed Allowing Full Access to Desktop, a
    vulnerability in MacOS X's screen saver allows local attackers to bypass
    it by sending it a large number of characters. Apple has now issued a
    patch to resolve this issue.

    DETAILS

    Apple has issued a security update (2003-07-14) to address a potential
    vulnerability when a password is required upon waking from the Screen
    Effects feature, which could allow an unauthorized user access to the
    desktop of the logged in user.

    The patch can be downloaded from:
