Vulnerability name/brief description MS13-068 - Critical Vulnerability in Microsoft Outlook Could Allow Remote Code Execution (2756473)
CVE/CAN name
Vendor threat level Critical
SophosLabs threat level High
Solution MS13-068
Vendor description This security update resolves a privately reported vulnerability in Microsoft Outlook. The vulnerability could allow remote code execution if a user opens or previews a specially crafted email message using an affected edition of Microsoft Outlook. An attacker who successfully exploited this vulnerability could gain the same user rights as the local user. Users whose accounts are configured to have fewer user rights on the system could be less impacted than users who operate with administrative user rights.
SophosLabs comments The vulnerability arises from the way Microsoft Outlook parses the contents of a S/MIME message. By specially crafting a S/MIME message, an attacker can potentially gain access to the victim's computer. Although the vulnerability was privately disclosed via responsible disclosure, S/MIME is an extremely popular Internet standard and one of the primary ways to transmit information across the Internet. SophosLabs has thus rated the Threat Level as High.
