Title: Microsoft Outlook vcard Buffer Overflow Vulnerability
Severity: HIGH
Description:
vCard (.vcf) files contain contact information such as address, telephone numbers, email, URLs and various other personal data. vCards, in essence, are electronic business cards.
Due to an unchecked buffer in Microsoft Outlook, it is possible for a remote user to execute arbitrary code on a victim's machine.
If a maliciously crafted .vcf file containing malformed data in the 'Birthday' field is sent as an attachment and executed, the maliciously embeded code could be run on the recipient's machine.
Successful exploitation of this vulnerability could lead to complete comprimise of the target host.
