Adobe Acrobat y Adobe Reader, en las versiones 2019.008.20081 y anteriores, en las 2019.008.20080 y anteriores, en las 2019.008.20081 y anteriores, en las 2017.011.30106 y anteriores, en las 2017.011.30105 y anteriores, en las 2015.006.30457 y anteriores y en las 2015.006.30456 y anteriores, podrían tener una vulnerabilidad de desreferencia de puntero no fiable. La explotación con éxito de esta vulnerabilidad podría permitir la ejecución arbitraria de código.

This vulnerability allows remote attackers to execute arbitrary code on vulnerable installations of Adobe Reader DC. User interaction is required to exploit this vulnerability in that the target must visit a malicious page or open a malicious file.
The specific flaw exists within the parsing of index files within Onix32.dll. The issue results from the lack of proper validation of a user-supplied value prior to dereferencing it as a pointer. An attacker can leverage this vulnerability to execute code in the context of the current process.
