Name of the Vulnerable Software and Affected Versions AbsoluteTelnet version 11.24

Description AbsoluteTelnet version 11.24 contains a denial of service issue that allows local attackers to crash the application. This is achieved by manipulating the username and error report fields. Specifically, inserting 1000 characters into the username or email address fields causes the application to become unresponsive.
