Descriptions

A vulnerability has been identified in JT2Go (All versions < V13.2.0.5), Teamcenter Visualization (All versions < V13.2.0.5). The VCRUNTIME140.dll is vulnerable to an out of bounds read past the end of an allocated buffer when parsing specially crafted CGM files. An attacker could leverage this vulnerability to leak information in the context of the current process. (ZDI-CAN-15109)

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 VCRUNTIME140.dll es vulnerable a una lectura fuera de límites más allá del final de un búfer asignado cuando son analizados archivos CGM especialmente diseñados. Un atacante podría aprovechar esta vulnerabilidad para filtrar información en el contexto del proceso actual. (ZDI-CAN-15109)

This vulnerability allows remote attackers to disclose sensitive information 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 CGM files. 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 buffer. An attacker can leverage this in conjunction with other vulnerabilities to execute arbitrary code in the context of the current process.
