OllyDBG Resource Directory Integer Overflow Vulnerability

OllyDBG is prone to an integer-overflow vulnerability because it fails to perform adequate boundary checks on user-supplied data before copying it into an insufficiently sized memory buffer.

Attackers may leverage this issue to execute arbitrary code in the context of the application. Failed attacks will cause denial-of-service conditions.

OllyDBG v1.10 is vulnerable; other versions may also be affected.
