Insufficient boundary checks when processing the JPEG APP12 block marker in the GD extension could allow access to out-of-bounds memory via a maliciously constructed invalid JPEG input. This issue affects HHVM versions prior to 3.30.9, all versions between 4.0.0 and 4.8.3, all versions between 4.9.0 and 4.15.2, and versions 4.16.0 to 4.16.3, 4.17.0 to 4.17.2, 4.18.0 to 4.18.1, 4.19.0, 4.20.0 to 4.20.1.

Las comprobaciones de límites insuficientes cuando se procesa el marcador de bloque JPEG APP12 en la extensión GD, podrían permitir el acceso a la memoria fuera de límites por medio de una entrada JPEG no válida construida maliciosamente. Este problema afecta a HHVM versiones anteriores a 3.30.9, todas las versiones entre 4.0.0 y 4.8.3, todas las versiones entre 4.9.0 y 4.15.2, y las versiones 4.16.0 hasta 4.16.3, 4.17.0 hasta 4.17.2 , 4.18.0 hasta 4.18.1, 4.19.0, y 4.20.0 hasta 4.20.1.
