Уязвимость программного обеспечения OpenVPN, связанная с использованием памяти после её освобождения, позволяющая нарушителю вызвать отказ в обслуживании

Уязвимость опции --fragment программного обеспечения OpenVPN, связанная с ошибками при делении на ноль, позволяющая нарушителю вызвать отказ в обслуживании

Уязвимость компонента Plug-in Handler программного обеспечения OpenVPN, позволяющая нарушителю загружать произвольные модули

Using the --fragment option in certain configuration setups OpenVPN version 2.6.0 to 2.6.6 allows an attacker to trigger a divide by zero behaviour which could cause an application crash, leading to a denial of service.

Use after free in OpenVPN version 2.6.0 to 2.6.6 may lead to undefined behavoir, leaking memory buffers or remote execution when sending network buffers to a remote peer.

The OpenVPN GUI installer before version 2.6.9 did not set the proper access control restrictions to the installation directory of OpenVPN binaries when using a non-standard installation path, which allows an attacker to replace binaries to run arbitrary executables.

The interactive service in OpenVPN 2.6.9 and earlier allows the OpenVPN service pipe to be accessed remotely, which allows a remote attacker to interact with the privileged OpenVPN interactive service.

The interactive service in OpenVPN 2.6.9 and earlier allows an attacker to send data causing a stack overflow which can be used to execute arbitrary code with more privileges.

OpenVPN plug-ins on Windows with OpenVPN 2.6.9 and earlier could be loaded from any directory, which allows an attacker to load an arbitrary plug-in which can be used to interact with the privileged OpenVPN interactive service.

OpenVPN from 2.6.0 through 2.6.10 in a server role accepts multiple exit notifications from authenticated clients which will extend the validity of a closing session

OpenVPN version 2.4.0 through 2.6.10 on Windows allows an external, lesser privileged process to create a named pipe which the OpenVPN GUI component would connect to allowing it to escalate its privileges

OpenVPN before 2.6.11 does not santize PUSH_REPLY messages properly which an attacker controlling the server can use to inject unexpected arbitrary data ending up in client logs.
