This bulletin addresses a vulnerability affecting the systems listed
below. There is a buffer overflow vulnerability in Microsoft's Jet
Database Engine (Jet). An attacker could take control of a vulnerable
system, including installing programs; viewing, changing, or deleting
data; or creating new accounts that have full privileges. This
vulnerability has been assigned VU#740716 and CAN-2004-0197.
Impact
Remote attackers could execute arbitrary code on vulnerable systems.

Update to TA04-099A
Microsoft has released a patch that addresses the cross-domain
vulnerability discussed in TA04-099A: "Vulnerability in Internet
Explorer ITS Protocol Handler". US-CERT is tracking this issue as
VU#323070. This reference number corresponds to CVE candidate
CAN-2004-0380.
The patches and further information about the vulnerability are
available in Microsoft Security Bulletin MS04-013. MS04-013 is titled
"Cumulative Security Update for Outlook Express". Since most (if not
all) current Windows systems have Outlook Express installed by
default, and the MHTML protocol handler is part of the Outlook Express
software package, most (if not all) Windows systems should be
considered vulnerable.
TA04-099A and VU#323070 focused on the ITS protocol handlers; however,
the latent vulnerability appears to be in the MHTML handler shipped as
part of Outlook Express. These documents have been updated.
II. Impact
Several of the issues identified by Microsoft have been described as
"Critical" in nature.Each bulletin contains at least one vulnerability
which may allow remote attackers to execute arbitrary code on affected
systems. The privileges gained would depend on the security context of
the software and vulnerability exploited.
III. Solution
Apply an appropriate set of updates from Microsoft
Please see the following site for more information about appropriate
remediation.
