Name of the Vulnerable Software and Affected Versions AgataSoft PingMaster Pro version 2.1

Description The software contains a denial of service issue within the Trace Route feature. An attacker can cause the application to crash by exploiting a buffer overflow in the host name input field. Specifically, providing a 10,000-character buffer to the hostname input can trigger the crash and potentially lead to system instability.

Recommendations Apply a fix that properly validates the length of the input provided to the hostname field in the Trace Route feature. As a temporary workaround, limit the number of characters allowed in the hostname input field.
