The cumulative Virtuozzo ReadyKernel patch was updated with security fixes. The patch applies to Virtuozzo kernels 3.10.0-514.16.1.vz7.30.10 (Virtuozzo 7.0.4) and 3.10.0-514.16.1.vz7.30.15 (Virtuozzo 7.0.4 HF3).
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: CVE-2017-7477
A flaw was found in the way Linux kernel allocates heap memory to build the scattergather list from a fragment list(skb_shinfo(skb)->frag_list) in the socket buffer(skb_buff). The heap overflow occurred if ‘MAX_SKB_FRAGS + 1’ parameter and ‘NETIF_F_FRAGLIST’ feature are both used together. A remote user or process could use this flaw to potentially escalate their privilege on a 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.
