Descriptions

A vulnerability has been identified in JT2Go (All versions < V13.2.0.5), Teamcenter Visualization (All versions < V13.2.0.5). The DL180pdfl.dll contains an out of bounds write past the end of an allocated structure while parsing specially crafted JT files. This could allow an attacker to execute code in the context of the current process. (ZDI-CAN-15103)

Se ha identificado una vulnerabilidad en JT2Go (Todas las versiones anteriores a V13.2.0.5), Teamcenter Visualization (Todas las versiones anteriores a V13.2.0.5). El archivo DL180pdfl.dll contiene una escritura fuera de límites más allá del final de una estructura asignada mientras analiza archivos JT especialmente diseñados. Esto podría permitir a un atacante ejecutar código en el contexto del proceso actual. (ZDI-CAN-15103)

This vulnerability allows remote attackers to execute arbitrary code on affected installations of Siemens JT2Go. 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 JT files. Crafted data in a JT file can trigger a write past the end of an allocated buffer. An attacker can leverage this vulnerability to execute code in the context of the current process.
