Microsoft GDI+ CVE-2012-0167 EMF Image Processing Buffer Overflow Vulnerability

Risk

High

Date Discovered

May 8, 2012

Description

Microsoft GDI+ is prone to a remote heap-based buffer-overflow vulnerability because it fails to properly bounds-check user-supplied input before copying it to an insufficiently sized buffer. An attacker can exploit this issue to execute arbitrary code with the privileges of the currently logged-in user. Failed exploit attempts may crash the affected application.

Recommendations

Run all software as a nonprivileged user with minimal access rights.

To reduce the impact of latent vulnerabilities, always run nonadministrative software as an unprivileged user with minimal access rights.

Deploy network intrusion detection systems to monitor network traffic for malicious activity.

Deploy NIDS to monitor network traffic for signs of anomalous or suspicious activity. This includes but is not limited to requests that include NOP sleds and unexplained incoming and outgoing traffic. This may indicate exploit attempts or activity that results from successful exploits.

Do not follow links provided by unknown or untrusted sources.

Web users should be cautious about following links to sites that are provided by unfamiliar or suspicious sources. Filtering HTML from emails may help remove a possible vector for transmitting malicious links to users.

Implement multiple redundant layers of security.

Since attackers may be able to execute arbitrary code, implement memory-protection schemes (such as nonexecutable stack and heap configurations and randomly mapped memory segments) to reduce the chance of a successful exploit.
The vendor released an advisory and fixes to address this issue. Please see the references for more information.
