CERT advisories always look like this, AFAIK. Remember, CERT was one of the groups that advised people stop using IE because of its many security holes.How long have you been reading them? The difference is in degree. They were really *shitsukoi* in that last one! Have a look at one from March of 2004 (below). Also note that in the March 2004 one, it is signed off as: "Carnegie Mellon University", and now it's: "US-CERT, a government organization" The drift to attack PR seems to have coincided with the departure of the Carnegie Mellon University name, which was something people respected. The new version is - apparently - not something to respect or trust.I doubt there is anything sinister going on here, but it is funny that someone else (Shannon?) mentioned yesterday at the meeting that the media have been beating up on Firefox / Mozilla / Thunderbird recently, and he suspects Microsoft influence. I responded that I was not that cynical, but allowed that there was a good chance that he might be right. So might you. I just hope not.I'm not happy about it, and I wish it weren't the case, but the content has gone foul, so I'm afraid he was right. Anyway, have a look at the March 2004 one as a comparison to the new attack-PR one. [From March 2004]: Microsoft Outlook mailto URL Handling Vulnerability Original issue date: March 10, 2004 Last revised: -- Source: US-CERT Systems Affected * Microsoft Office XP (up to Service Pack 2) * Microsoft Outlook 2002 (up to Service Pack 2) Overview A vulnerability in the way that Microsoft Outlook 2002 handles a certain type of URL could allow a remote attacker to execute arbitrary code on the vulnerable system. I. Description Microsoft Outlook provides a centralized application for managing and organizing email messages, schedules, tasks, notes, contacts, and other information. Outlook is included as a component of newer versions of Microsoft Office and available as a stand-alone product. Outlook 2002 exposes a vulnerability due to inadequate checking of parameters passed to the Outlook email client. The vulnerability is caused by the way a "mailto:" URL is interpreted. An attacker creating specially formatted "mailto:" URLs can cause Outlook to run privileged script, ultimately leading to the execution of arbitrary code. The malicious code could be delivered to the victim via a specially crafted HTML email message or from an intruder-controlled web page. Microsoft originally stated that users were only at risk from this vulnerability when Outlook 2002 is configured as the default mail reader and when the "Outlook Today" home page is their default folder home page. Subsequent information has been published that indicates that this is not true and users in other situations are vulnerable via a slightly different attack vector. II. Impact An attacker could execute arbitrary code of their choosing on the system running the vulnerable version of Outlook. Upon successful exploitation, the malicious code would be executed in the context of the "Local Machine" Internet Explorer zone under the user running Outlook. III. Solution Apply a patch Apply the appropriate patch as specified by Microsoft Security Bulletin MS04-009. Workarounds Microsoft recommends the following workarounds for users who are unable to apply the patches: * Do not use the "Outlook Today" folder home page in Outlook 2002 You can help protect against this vulnerability by turning off the "Outlook today" folder home page in Outlook 2002. 1. In the "Folder List" window of Outlook, right-click on "Outlook Today" or "Mailbox - [User Name]" 2. Select Properties for "Outlook Today" or "Mailbox - [User Name]" 3. Select "Home Page" tab 4. Uncheck "Show home page by default for this folder" 5. Repeat for all other "Folder List" items labeled "Outlook Today" or "Mailbox - [User Name]" Impact of Workaround: The "Outlook Today" folder home page would no longer be available. * If you are using Outlook 2002 or Outlook Express 6.0 SP1 or later, read email messages in plain text format to help protect yourself from the HTML email attack vector Microsoft Outlook 2002 users who have applied Service Pack 1 or later and Outlook Express 6.0 users who have applied Service Pack 1 or later can enable a feature that will enable them to view all non-digitally-signed email messages or non-encrypted email messages in plain text only. Digitally-signed email messages and encrypted email messages are not affected by the setting and may be read in their original formats. Instructions for enabling these settings can be found at the following locations: + Outlook 2002 - Microsoft Knowledge Base Article 307594 + Outlook Express 6.0 - Microsoft Knowledge Base Article 291387 Impact of Workaround: Email that is viewed in plain text format cannot contain pictures, specialized fonts, animations, or other rich content. Additionally: + The changes are applied to the preview pane and to open messages. + Pictures become attachments to avoid loss of message content. + The object model (custom code solutions) may behave unexpectedly because the message is still in Rich Text Format or in HTML format in the mail store.
