Descriptions

procps-ng before version 3.3.15 is vulnerable to a denial of service in ps via mmap buffer overflow. Inbuilt protection in ps maps a guard page at the end of the overflowed buffer, ensuring that the impact of this flaw is limited to a crash (temporary denial of service).

procps-ng en versiones anteriores a la 3.3.15 es vulnerable a una denegación de servicio (DoS) en ps mediante un desbordamiento de búfer en mmap. La protección incluida en ps mapea una página guard al final del búfer desbordado, asegurando que el impacto de este error se limita a un cierre inesperado (denegación de servicio temporal).

Qualys performed an extensive audit of procps-ng. They discovered hundreds of bugs and vulnerabilities.
