CVE-2019-25705 is a high-severity flaw (CVSS 8.4) affecting echo mirage. Below: why it ranks where it does, which versions are affected, what to do, and the exact commands.

Echo Mirage 3.1 contains a stack buffer overflow vulnerability that allows local attackers to crash the application or execute arbitrary code by supplying an oversized string in the Rules action field. Attackers can create a malicious text file with a crafted payload exceeding buffer boundaries and paste it into the action field through the Rules dialog to trigger the overflow and overwrite the return address.
