A buffer overflow in OpenConnect could result in execution of
arbitrary code or Denial of Service.
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:
