Vulnerability name/brief description MS13-074 - Important Vulnerabilities in Microsoft Access Could Allow Remote Code Execution (2848637)
CVE/CAN name
Vendor threat level Important
SophosLabs threat level Medium
Solution MS13-074
Vendor description This security update resolves three privately reported vulnerabilities in Microsoft Office. The vulnerabilities could allow remote code execution if a user opens a specially crafted Access file with an affected version of Microsoft Access. An attacker who successfully exploited the vulnerabilities could gain the same user rights as the current 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 This vulnerability arises due to the way Microsoft Access handles memory when opening specially crafted Access files. Certain database queries can lead to incorrect memory validation errors. Under such a circumstance, the attacker can use the error to run arbitrary code on the victim's computer. Although the vulnerabilities are privately reported, SophosLabs nevertheless recommends that the patch be applied as soon as possible.
