TITLE:

SECUNIA ADVISORY ID:
SA36250
VERIFY ADVISORY:
http://secunia.com/advisories/36250/
DESCRIPTION:
webDEViL has discovered a vulnerability in Microsoft Windows, which
can be exploited by malicious people and by malicious, local users to
cause a DoS (Denial of Service).
The vulnerability is caused due to an error in win32k.sys when
processing Embedded OpenType fonts. This can be exploited to crash an
affected system when e.g. an HTML page embedding a malicious font is
opened.
NOTE: A system crash can occur if an administrator visits a malicious
website, or if an unprivileged user opens a malicious, locally stored
HTML page.
The vulnerability is confirmed on a fully patched Microsoft Windows
Server 2003 SP2. Other versions may also be affected.
SOLUTION:
Do not browse untrusted websites or follow untrusted links.
Restrict local access to trusted users only.
