Description Agostino Sarubbo gentoo-dev 2013-01-10 15:46:42 UTC
From $URL :

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 users into 
using a malicious host file.

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

No official solution is currently available.
