Trust: 2.1

sources: ZDI: ZDI-19-798 // ZDI: ZDI-19-762 // ZDI: ZDI-19-763

DESCRIPTION

Multiple buffer overflow issues have been identified in Alpha5 Smart Loader: All versions prior to 4.2. An attacker could use specially crafted project files to overflow the buffer and execute code under the privileges of the application. Alpha5 Smart Loader Contains a buffer error vulnerability.Information is obtained, information is altered, and service operation is disrupted (DoS) There is a possibility of being put into a state. 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 PLD 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.
