Descriptions
sapi/fpm/fpm/fpm_log.c in PHP before 5.5.31, 5.6.x before 5.6.17, and 7.x before 7.0.2 misinterprets the semantics of the snprintf return value, which allows attackers to obtain sensitive information from process memory or cause a denial of service (out-of-bounds read and buffer overflow) via a long string, as demonstrated by a long URI in a configuration with custom REQUEST_URI logging.
sapi/fpm/fpm/fpm_log.c en PHP en versiones anteriores a 5.5.31, 5.6.x en versiones anteriores a 5.6.17 y 7.x en versiones anteriores a 7.0.2 malinterpreta la semántica del valor de retorno snprinfg, lo que permite a atacantes remotos obtener información sensible del proceso de memoria o provocar una denegación de servicio (lectura fuera de rango y desbordamiento de búfer) a través de una cadena larga, como se demuestra por una URl larga en una configuración con inicio de sesión REQUEST_URI personalizado.
An out-of-bounds write flaw was found in the fpm_log_write() logging function of PHP's FastCGI Process Manager service. A remote attacker could repeatedly send maliciously crafted requests to force FPM to exhaust file system space, creating a denial of service and preventing further logging.
