The cumulative Virtuozzo ReadyKernel patch was updated with security fixes. The patch applies to Virtuozzo kernels 3.10.0-327.18.2.vz7.15.2 (Virtuozzo 7.0.0), 3.10.0-327.36.1.vz7.18.7 (Virtuozzo 7.0.1), and 3.10.0-327.36.1.vz7.20.18 (Virtuozzo 7.0.3).
Vulnerability id: CVE-2017-8797
The NFSv4 server in the Linux kernel compiled with CONFIG_NFSD_PNFS enabled does not properly validate layout type when processing NFSv4 pNFS LAYOUTGET and GETDEVICEINFO operands. The attack payload fits to single one-way UDP packet. The provided input value is used for array dereferencing. This may lead to a remote DoS of [knfsd] and so to a soft-lockup of a whole system.
Vulnerability id: PSBM-64752
A vulnerability was found in the implementation of setsockopt() operations in the Linux kernel. A privileged user inside a container could cause a DoS attack on the host (kernel deadlock in ip_ra_control() function) using a specially crafted sequence of system calls.
