A buffer overflow attack is reported when an attempt is made to exploit a running process using buffer overflow techniques.
A buffer overflow occurs when certain memory areas of a running process are overwritten with data in a manner not anticipated by its developers. An attacker can supply this data to target existing process vulnerabilities, enabling malicious code to gain unauthorized access to the system.
Not all files or processes that overflow buffers are security risks. In cases where you believe the process is not a threat, you can authorize it. If you are not sure whether a file is a security risk, you can send the file to SophosLabs for analysis.
