Descriptions

An issue was discovered in Adobe Acrobat and Reader: 2017.012.20098 and earlier versions, 2017.011.30066 and earlier versions, 2015.006.30355 and earlier versions, and 11.0.22 and earlier versions. This vulnerability leads to a stack-based buffer overflow condition in the internal Unicode string manipulation module. It is triggered by an invalid PDF file, where a crafted Unicode string causes an out of bounds memory access of a stack allocated buffer, due to improper checks when manipulating an offset of a pointer to the buffer. Attackers can exploit the vulnerability and achieve arbitrary code execution if they can effectively control the accessible memory.

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 conduce a un desbordamiento de búfer basado en pila en el módulo de manipulación de cadenas Unicode internas. Se desencadena por medio de un archivo PDF inválido, en el que una cadena Unicode manipulada provoca un acceso a la memoria fuera de límites de un búfer asignado a la pila. Esto se debe a las comprobaciones incorrectas al manipular un offset de un puntero en un búfer. Los atacantes pueden explotar esta vulnerabilidad y lograr la ejecución de código arbitrario si pueden controlar de manera efectiva la memoria accesible.

This vulnerability allows remote attackers to disclose sensitive information on vulnerable installations of Adobe Acrobat Pro 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 PDF Forms. The issue results from the lack of proper validation of user-supplied data, which can result in a read past the end of an allocated object. An attacker can leverage this in conjunction with other vulnerabilities to execute code in the context of the current process.
