CVE-2017-16362

Estado: ModificadaAlta (8.8)—

Se ha descubierto un problema en Adobe Acrobat y Reader: 2017.012.20098 y versiones anteriores, 2017.011.30066 y versiones anteriores, 2015.006.30355 y versiones anteriores y 11.0.22 y versiones anteriores. La vulnerabilidad es un ejemplo de lectura fuera de límites en el plugin MakeAccesible, al manipular datos de fuentes. Provoca un acceso a la memoria fuera de límites, lo que, a veces, desencadena una excepción de violación de acceso. Los atacantes pueden explotar esta vulnerabilidad empleando el acceso fuera de límites para lecturas, escrituras o liberaciones no planeadas. Esto podría desembocar en la corrupción de código, secuestro del flujo de control o un ataque de filtrado de información.

This vulnerability is an instance of an out of bounds read vulnerability in the MakeAccesible plugin, when handling font data. It causes an out of bounds memory access, which sometimes triggers an access violation exception. Attackers can exploit the vulnerability by using the out of bounds access for unintended reads, writes, or frees, potentially leading to code corruption, control-flow hijack, or an information leak attack."
