Assigner: VulnCheck

Description
Prime95 29.4b7 contains a buffer overflow vulnerability in the PrimeNet connection dialog that allows local attackers to crash the application by supplying an excessively long string in the optional proxy password field. Attackers can trigger a denial of service by entering a 6000-byte payload into the proxy password parameter, causing the application to crash when processing the connection settings.

Executive Summary

This vulnerability exists in Prime95 version 29.4b7 within the PrimeNet connection dialog. It is a buffer overflow issue caused by the application accepting an excessively long string in the optional proxy password field.

Local attackers can exploit this by entering a very long input (for example, a 6000-byte payload) into the proxy password parameter, which causes the application to crash when it processes the connection settings.

Impact Analysis

The primary impact of this vulnerability is a denial of service (DoS). An attacker with local access can cause the Prime95 application to crash by supplying an overly long proxy password string.

This crash disrupts normal operation, potentially causing loss of service or interruption in any processes relying on Prime95.
