Bug affected | Squid prior 2.4.STABLE7 (e.g. on Red Hat Linux 6.2, 7.0, 7.1 and 7.2) |
Bug not affected | Squid prior 2.4.STABLE7 and newer or other proxy solutions |
Bug vulnerability class | Buffer Overflow |
Bug description | The remote host seems to be running a Squid proxy. Squid prior 2.4.STABLE7 is vulnerable to various buffer overflows. An attacker may crash the remote proxy or be able to run arbitrary code in the context of the server. |
Bug solution | The server should be deactivated or de-installed if not necessary. If this is not possible, you should upgrade the software to the latest versionTo make it harder to find the server the daemon could be configured to listen at another port (e.g. 8099). Try to prevent unwanted connection attempts by filtering traffic with firewalling. Alternation of the application banner can confuse an attacker and let him determine the wrong software. |
