OpenConnect is a free client for Cisco AnyConnect SSL VPN software.
A stack-based buffer overflow error has been discovered in OpenConnect.
A remote attacker could entice a user to connect to a malicious VPN server, possibly resulting in execution of arbitrary code with the privileges of the process, or a Denial of Service condition.
There is no known workaround at this time.
All OpenConnect users should upgrade to the latest version:
# emerge --sync # emerge --ask --oneshot --verbose ">=net-misc/openconnect-4.08"
