CVE-2018-25293: Prime95 29.4b7 Denial of Service via Proxy Password Field

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.

Security readout for executives and security teams

Prime95 29.4b7 has a local denial-of-service flaw in its PrimeNet connection settings. A user or local attacker who can reach the application settings can crash the application by entering an oversized value in the optional proxy password field. Exposure appears limited to systems running Prime95 29.4b7 where a local user or local attacker can interact with the PrimeNet connection configuration. This is not described as a remotely reachable service vulnerability in the provided bundle. Treat as a moderate-priority desktop/application availability issue. Prioritize remediation on shared systems, operational workstations, or environments where a Prime95 crash could interrupt business workflows; otherwise handle through normal vulnerable software removal or upgrade processes. Mitigation focus: Identify and remove or replace Prime95 29.4b7 where it is installed, especially on shared workstations or systems where untrusted local users have access.; No patched version is identified in the provided bundle; check Mersenne/Prime95 vendor guidance before selecting a fixed or supported replacement version.; Restrict local access to systems running the affected version until remediation is complete..
