Descriptions

Fuji Electric Alpha5 SMART is vulnerable to a stack-based buffer overflow, which may allow an attacker to execute arbitrary code.

This vulnerability allows remote attackers to execute arbitrary code on affected installations of Fuji Electric Alpha5 Smart. 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 C5V files. The issue results from the lack of proper validation of the length of user-supplied data prior to copying it to a stack-based buffer. An attacker can leverage this vulnerability to execute code in the context of the current process.
