The remote Virtuozzo host is missing a security update.


According to the version of the vzkernel package and the readykernel-patch installed, the Virtuozzo installation on the remote host is affected by the following vulnerability :

- A vulnerability was found in the signal handling in the Linux kernel. A local unprivileged user could cause a kernel crash (general protection fault) in the cleanup_timers() function by using the rt_tgsigqueueinfo() system call with a specially crafted set of arguments.
