Descriptions
An issue was discovered in PHP before 5.6.36, 7.0.x before 7.0.30, 7.1.x before 7.1.17, and 7.2.x before 7.2.5. ext/ldap/ldap.c allows remote LDAP servers to cause a denial of service (NULL pointer dereference and application crash) because of mishandling of the ldap_get_dn return value.
Se ha descubierto un problema en PHP en versiones anteriores a la 5.6.36, versiones 7.0.x anteriores a la 7.0.30, versiones 7.1.x anteriores a la 07.1.17 y versiones 7.2.x anteriores a la 7.2.5. ext/ldap/ldap.c permite que servidores LDAP remotos provoquen una denegación de servicio (desreferencia de puntero NULL y cierre inesperado de la aplicación) debido a la gestión incorrecta del valor de retorno ldap_get_dn.
It was discovered that PHP incorrectly handled opcache access controls when configured to use PHP-FPM. A local user could possibly use this issue to obtain sensitive information from another user's PHP applications. It was discovered that the PHP iconv stream filter incorrect handled certain invalid multibyte sequences. A remote attacker could possibly use this issue to cause PHP to hang, resulting in a denial of service. Various other issues were also addressed.
