Descriptions
In NetHack before 3.6.5, unknown options starting with -de and -i can cause a buffer overflow resulting in a crash or remote code execution/privilege escalation. This vulnerability affects systems that have NetHack installed suid/sgid and shared systems that allow users to influence command line options. Users should upgrade to NetHack 3.6.5.
En NetHack versiones anteriores a 3.6.5, las opciones desconocidas que comienzan con -de y -i pueden causar un desbordamiento del búfer resultando en un bloqueo o en una ejecución de código remota/escalada de privilegios. Esta vulnerabilidad afecta a los sistemas que tienen instalado suid/sgid de NetHack y sistemas compartidos que permiten a usuarios influir en las opciones de línea de comandos. Los usuarios deberían actualizar a NetHack versión 3.6.5.
