Descriptions

Stack-based buffer overflow in IBM Forms Viewer 4.x before 4.0.0.3 and 8.x before 8.0.1.1 allows remote attackers to execute arbitrary code via an XFDL form with a long fontname value.

El desbordamiento de búfer en la región stack de la memoria en Forms Viewer de IBM versiones 4.x anterior a 4.0.0.3 y la versiones 8.x anterior a 8.0.1.1, permite a los atacantes remotos ejecutar código arbitrario por medio de un formulario XFDL con un formulario largo valor fontname.

This vulnerability allows remote attackers to execute arbitrary code on vulnerable installations of IBM Forms Viewer. 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 a document handler of an XFDL document. The parsing of the 'fontname' tag with a large value can lead to a stack buffer overflow. A remote attacker can exploit this vulnerability to execute arbitrary code under the context of the process.
