Description:
Some vulnerabilities have been reported in Microsoft Outlook, which can be exploited by malicious people to cause a DoS (Denial of Service) or compromise a user's system.

1) An error within the processing of VEVENT records can be exploited to corrupt memory via a specially crafted .ICS (iCal) meeting request.

Successful exploitation allows execution of arbitrary code.

2) An error within the processing of e-mail header information can be exploited to crash the mail client via a specially crafted e-mail. In order to restore functionality, the malicious e-mail has to be removed manually from the mail server.

3) An error within the processing of Office Saved Searches (.oss) files can be exploited to corrupt memory by tricking a user into opening a specially crafted .oss file.

Successful exploitation allows execution of arbitrary code.

Solution:
Apply patches.
