Microsoft Outlook contains a memory corruption vulnerability that could enable an attacker to execute arbitrary code and gain complete control of the vulnerable system.
Microsoft Outlook fails to properly handle malformed VEVENT
records. When an .iCal
meeting request containing a VEVENT
record is opened, Outlook does not properly perform data validation on the record. An attacker could send a specially crafted .ics
file in the request that, when opened, could corrupt system memory allowing the attacker to execute arbitrary code. The attacker could then install programs; view, change, or delete data; or create new accounts with full user rights.
An attacker could gain complete control of the affected system and execute arbitrary code.
Microsoft addresses this vulnerability with the updates listed in Microsoft Security Bulletin MS07-003. Note that Microsoft has documented known issues that occur after applying this update. See Microsoft Knowledgebase article 925938 for details.
Users whose accounts are configured to have fewer user rights on the system could be less affected than users who operate with administrative user rights.
