Descriptions

An issue was discovered in PHP 7.x before 7.1.27 and 7.3.x before 7.3.3. phar_tar_writeheaders_int in ext/phar/tar.c has a buffer overflow via a long link value. NOTE: The vendor indicates that the link value is used only when an archive contains a symlink, which currently cannot happen: "This issue allows theoretical compromise of security, but a practical attack is usually impossible.

** EN DISPUTA ** Se ha detectado un fallo en PHP, en las versiones 7.x anteriores a la 7.1.27 y en las 7.3.x anteriores a la 7.3.3. phar_tar_writeheaders_int tiene un desbordamiento de búfer mediante un valor de enlace largo. NOTA: el fabricante indica que el valor de enlace se utiliza solamente cuando un archivo contiene un symlink, algo que actualmente no puede ocurrir: "Este fallo facilita el compromiso teórico de la seguridad. Sin embargo, un ataque práctico es normalmente imposible."
