Descriptions

The ZIP signature-verification feature in PHP before 5.6.26 and 7.x before 7.0.11 does not ensure that the uncompressed_filesize field is large enough, which allows remote attackers to cause a denial of service (out-of-bounds memory access) or possibly have unspecified other impact via a crafted PHAR archive, related to ext/phar/util.c and ext/phar/zip.c.

La funcionalidad de verificación de firma ZIP en PHP en versiones anteriores a 5.6.26 y 7.x en versiones anteriores a 7.0.11 no asegura que el campo uncompressed_filesize sea suficientemente grande, lo que podría permitir a atacantes remotos provocar una denegación de servicio (acceso a memoria fuera de límites) o tener otro posible impacto no especificado a través de una archivo PHAR manipulado, relacionado con ext/phar/util.c y ext/phar/zip.c.
