This vulnerability allows remote attackers to execute arbitrary code on vulnerable installations of Eaton ELCSoft. 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 a SegCmt record in an EPC file. The issue results from the lack of proper validation of the length of user-supplied data prior to copying it to a fixed-length stack-based buffer. An attacker can leverage this vulnerability to execute arbitrary code under the context of the current process.
