Synopsis
========
Multiple vulnerabilities have been found in Ettercap, the worst of
which may allow execution of arbitrary code.
Background
==========
Ettercap is a suite of tools for content filtering, sniffing and man in
the middle attacks on a LAN.
Affected packages
=================
-------------------------------------------------------------------
Package / Vulnerable / Unaffected
-------------------------------------------------------------------
1 net-analyzer/ettercap < 0.7.5.2 >= 0.7.5.2
Description
===========
Multiple vulnerabilities have been discovered in Ettercap:
* Ettercap does not handle temporary files securely (CVE-2010-3843).
* A format string flaw in Ettercap could cause a buffer overflow
(CVE-2010-3844).
* A stack-based buffer overflow exists in Ettercap (CVE-2013-0722).
Impact
======
A remote attacker could entice a user to load a specially crafted
configuration file using Ettercap, possibly resulting in execution of
arbitrary code with the privileges of the process or a Denial of
Service condition.
A local attacker could perform symlink attacks to overwrite arbitrary
files with the privileges of the user running the application.
Workaround
==========
There is no known workaround at this time.
Resolution
==========
All Ettercap users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose ">=net-analyzer/ettercap-0.7.5.2"
