Descriptions

Adobe Framemaker versions 2019.0.4 and below have a heap overflow vulnerability. Successful exploitation could lead to arbitrary code execution.

Adobe Framemaker versiones 2019.0.4 y posteriores, presenta una vulnerabilidad de desbordamiento de la pila. Una explotación con éxito podría conllevar a una ejecución de código arbitrario.

This vulnerability allows remote attackers to execute arbitrary code on affected installations of Adobe FrameMaker. 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 CEL files. When parsing CEL files, the process does not properly validate the length of user-supplied data prior to copying it to a fixed-length, heap-based buffer. An attacker can leverage this vulnerability to execute code in the context of the current process.
