The cumulative Virtuozzo ReadyKernel patch updated with security fixes. The patch applies to Virtuozzo versions 7.0.0, 7.0.1, and 7.0.3.
Vulnerability id: CVE-2017-6074
A use-after-free flaw was found in the way the Linux kernel’s Datagram Congestion Control Protocol (DCCP) implementation freed SKB (socket buffer) resources for a DCCP_PKT_REQUEST packet when the IPV6_RECVPKTINFO option is set on the socket. A local, unprivileged user could use this flaw to alter the kernel memory, allowing them to escalate their privileges on the system.
Vulnerability id: CVE-2016-2053
A syntax vulnerability was discovered in the kernel’s ASN1.1 DER decoder, which could lead to memory corruption or a complete local denial of service through x509 certificate DER files. A local system user could use a specially created key file to trigger BUG_ON() in the public_key_verify_signature() function (crypto/asymmetric_keys/public_key.c), to cause a kernel panic and crash the system.
