Descriptions

In PHP before 5.6.32, 7.x before 7.0.25, and 7.1.x before 7.1.11, an error in the date extension's timelib_meridian handling of 'front of' and 'back of' directives could be used by attackers able to supply date strings to leak information from the interpreter, related to ext/date/lib/parse_date.c out-of-bounds reads affecting the php_parse_date function. NOTE: this is a different issue than CVE-2017-11145.

En PHP, en versiones anteriores a la 5.6.32, versiones 7.x anteriores a la 7.0.25 y versiones 7.1.x anteriores a la 7.1.11, un error en la manipulación de timelib_meridian de la extensión de fecha de las directivas "front of" y "back of" podría ser empleado por atacantes capaces de proporcionar cadenas de fechas para filtrar información del intérprete. Esto está relacionado con lecturas fuera de límites de ext/date/lib/parse_date.c que afectan a la función php_parse_date. NOTA: este problema es diferente de CVE-2017-11145.
