Autonomy KeyView Module Excel Document Processing Buffer Overflow Vulnerability

Risk

High

Date Discovered

August 25, 2009

Description

Autonomy KeyView module is prone to a buffer-overflow vulnerability because it fails to perform adequate boundary checks on user-supplied data before copying it to insufficiently sized buffers. Exploiting this issue will allow an attacker to corrupt memory and cause denial-of-service conditions or potentially to execute arbitrary code in the context of an application using the module. Multiple products using the KeyView module are affected.

Recommendations

Block external access at the network boundary, unless external parties require service.

Filter access to the affected computer at the network boundary if global access isn't needed. Restricting access to only trusted computers and networks might greatly reduce the likelihood of a successful exploit.

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.

Implement multiple redundant layers of security.

Various memory-protection schemes (such as nonexecutable and randomly mapped memory segments) may hinder an attacker's ability to exploit this vulnerability to execute arbitrary code.
Vendor updates are available. Please see the references for details.
