Descriptions

The affected product is vulnerable to a heap-based buffer overflow, which may lead to code execution.

El producto afectado es vulnerable a un desbordamiento de búfer en la región heap de la memoria, que puede conllevar a una ejecución de código

This vulnerability allows remote attackers to execute arbitrary code on affected installations of Fuji Electric Alpha5. 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 C5P files in the Server Operator module. The issue results from the lack of proper validation of the length of user-supplied data prior to copying it to a heap-based buffer. An attacker can leverage this vulnerability to execute code in the context of the current process.
