The remote Virtuozzo host is missing a security update.


According to the version of the parallels-server-bm-release / vzkernel / etc packages installed, the Virtuozzo installation on the remote host is affected by the following vulnerability :

- A flaw was discovered in the Linux kernel's key subsystem. Invoking the request_key() system call with a specially crafted set of arguments could result in a NULL-pointer dereference inside the search_keyring() function. A local unprivileged user could use this vulnerability to crash the system. The vulnerability could be exploited from inside containers.
