Description


A vulnerability has been discovered in Ettercap, which can be exploited by malicious people to compromise a user's system.

The vulnerability is caused due to a boundary error within the "scan_load_hosts()" function (src/ec_scan.c) when parsing entries from hosts list, which can be exploited to cause a stack-based buffer overflow via an overly long entry.

Successful exploitation may allow execution of arbitrary code but requires tricking a user into using a malicious hosts file.

The vulnerability is confirmed in version 0.7.5.1. Other versions may also be affected.


Solution:
Update to version 0.7.5.2.
