The Sophos Antivirus Library provides file format support for virus analysis. During analysis of Visio files Sophos is vulnerable to a heap overflow allowing attackers complete control of the system(s) being protected. This vulnerability can be exploited remotely without user interaction or authentication through common protocols such as SMTP, SMB, HTTP, FTP, etc.
Successful exploitation of Sophos protected systems allows attackers unauthorized control of data and related privileges. It also provides leverage for further network compromise. Sophos Antivirus Library implementations are likely vulnerable in their default configuration.
