CVE/CAN name
Vendor threat level Important
SophosLabs threat level low
Solution MS13-071
Vendor description This security update resolves a privately reported vulnerability in Microsoft Windows. The vulnerability could allow remote code execution if a user applies a specially crafted Windows theme on their system. In all cases, a user cannot be forced to open the file or apply the theme; for an attack to be successful, a user must be convinced to do so.
SophosLabs comments This privately reported vulnerability would require local access to the victim's computer in order to take advantage of the vulnerability and compromise the victim's computer. Although the method of attack is rudimentary, this vulnerability can manifest itself in other ways (eg. introduced by other Trojans or worms), further compromising the victim's computer and using it for other nefarious purposes. Although the Threat Level is set to Low, SophosLabs still recommends that this update be applied as soon as it is made available.
