Descriptions

The Datalogics APDFL library used in affected products is vulnerable to memory corruption condition while parsing specially crafted PDF files. An attacker could leverage this vulnerability to execute code in the context of the current process.

La librería Datalogics APDFL utilizada en los productos afectados es vulnerable a daños en la memoria al analizar archivos PDF especialmente manipulados. Un atacante podría aprovechar esta vulnerabilidad para ejecutar código en el contexto del proceso actual.

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 PDF 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.

*Credits: Mat Powell of Trend Micro’s Zero Day Initiative reported these vulnerabilities to Siemens and CISA.
