CVE-2016-1626

Estado: ModificadaMedia (4.3)—

La función opj_pi_update_decode_poc en pi.c en OpenJPEG, como se utiliza en PDFium en Google Chrome en versiones anteriores a 48.0.2564.109, no calcula correctamente un determinado valor de índice de capa, lo que permite a atacantes remotos causar una denegación de servicio (lectura fuera de rango) a través de un documento PDF manipulado.
