NASA Ames Research Center BigView PNM File Stack-Based Buffer Overflow Vulnerability

NASA Ames Research Center BigView is prone to a remote stack-based buffer-overflow vulnerability because it fails to properly bounds-check user-supplied data before copying it to an insufficiently sized memory buffer.

An attacker can exploit this issue to execute arbitrary code in the context of the application. Successful attacks will compromise the application and underlying computer. Failed exploit attempts will result in a denial of service.

BigView 1.8 is vulnerable; other versions may also be affected.
