Re: Outlook causing access protection error?

I, too, have noticed this problem, starting the morning of 3/17.

We have McAfee VS Enterprise 8.5.0i, scan engine 5400.1158, current DAT version 5924.0000 (although it started on 3/17 with an earlier DAT).

Also on machines of users with admin privilege.

Re: Outlook causing access protection error?

Got this from Support.

It looks like the problem is being caused by the new BOP(Buffer Overflow Protection) DAT update that went out on March 16th. The new version 480 vscan.bof file (Buffer Overflow and Access Protection rules file) has a change in it that can results this kind of problem.

They are working on a fix but the work around is to exclude Outlook.exe from the protection rules.

Will post an update when they come back with the fix.

Within two weeks they will have a fix.

Tech stated they were just going to put in an internal exception. I really hope he was hearing them wrong.

Re: Outlook causing access protection error?

McAfee posted a response in the other thread relating to this issue;

Hello Everyone

Just to give you all some assurance here as to what is happening.

McAfee is aware of this behaviour occuring on machines running VirusScan 8.5 primarily. This issue seems to have occured when a new Buffer Overflow DAT was released on the 16th March 2010 which was version 480

I can assure you all that this issue is being investigated by McAfee seniors and should be fixed with a new BOC DAT update. This is most likely to be version 491 and should be released soon.

In the meantime, a workaround would be to add Outlook.exe as an exclusions in the rule of Access Protection that is being triggered.

Hope this helps.

Re: Outlook causing access protection error?

Looks like this has been cured, no notification from McAfee but checked our ePO this morning and we have updated

Buffer Overflow DAT for VirusScan EnterpriseDAT


Checked out fat clients and citrix servers and the error has now gone

Re: Outlook causing access protection error?

I can confirm receiving the 493 version of Buffer Overflow and Access Protection, however I did not see any mention of this upgrade in the daily DAT email, is there any other way McAfee alerts customers when this is updated?

Re: Outlook causing access protection error?

Our users have started to see this McAfee notifications related outlook.exe. I know this is known issue but is there any permanent fix other than adding outlook.exe  as exlusion in Access Protection.

Please update me.
