    John Heasman of NGSSoftware has discovered a high risk vulnerability in the
    Microsoft Windows kernel. The vulnerability (CAN-2005-0060) permits a
    logged-on user to escalate privileges to take full control of the system
    when Windows processes certain types of font.

    Microsoft has developed a patch to fix the problem. More information can be
    found here:

    http://www.microsoft.com/technet/security/bulletin/MS05-018.mspx

    NGSSoftware are going to withhold details about this flaw for three months.
    Full details will be published on the Tuesday, 12th of July 2005. This three
    month window will allow Microsoft customers the time needed to test and
    apply the patch before the details are released to the general public. This
    reflects NGSSoftware's new approach to responsible disclosure.

    Typhon III, NGSSoftware's advanced vulnerability assessment scanner, has
    been updated to check for and positively identify this flaw. More

NTBugtraq Editor's Note:
Most viruses these days use spoofed email addresses. As such, using an Anti-Virus product which automatically notifies the perceived sender of a message it believes is infected may well cause more harm than good. Someone who did not actually send you a virus may receive the notification and scramble their support staff to find an infection which never existed in the first place. Suggest such notifications be disabled by whomever is responsible for your AV, or at least that the idea is considered.
