An integer overflow vulnerability exists in the way ESTsoft Alyac 2.5.8.544 parses OLE files. A specially-crafted OLE file can lead to a heap buffer overflow which can result in arbitrary code execution. An attacker can provide a malicious file to trigger this vulnerability.
The product performs a calculation to determine how much memory to allocate, but an integer overflow can occur that causes less memory to be allocated than expected, leading to a buffer overflow.
