Name of the Vulnerable Software and Affected Versions Ettercap version 0.8.2

Description The issue allows remote attackers to cause a denial of service, resulting in a heap-based buffer overflow and application crash, or possibly have other unspecified impacts. This is achieved by using a crafted filter that is mishandled by etterfilter.

Recommendations For Ettercap version 0.8.2, consider avoiding the use of crafted filters until a patch is available. As a temporary workaround, restrict the use of the strescape function in ec strings.c to minimize the risk of exploitation.
