HPE Security Bulletin HPESBHF03800 1 - Remote denial of service and local elevation of privilege security vulnerabilities have been identified in HPE Comware 7 MSR Routers running software earlier than the R0605P20 release. Revision 1 of this advisory.
fb513de437b8d51d95b1e198d06970921be35743203d74648a285feab330ccd6Ubuntu Security Notice 3312-2 - USN-3312-1 fixed vulnerabilities in the Linux kernel for Ubuntu 16.04 LTS. This update provides the corresponding updates for the Linux Hardware Enablement kernel from Ubuntu 16.04 LTS for Ubuntu 14.04 LTS. It was discovered that the netfilter netlink implementation in the Linux kernel did not properly validate batch messages. A local attacker with the CAP_NET_ADMIN capability could use this to expose sensitive information or cause a denial of service. Various other issues were also addressed.

A local attacker with the CAP_NET_ADMIN capability could use this to expose sensitive information or cause a denial of service. Qian Zhang discovered a heap-based buffer overflow in the tipc_msg_build function in the Linux kernel. A local attacker could use to cause a denial of service or possibly execute arbitrary code with administrative privileges. Various other issues were also addressed.

A privileged local attacker could use this to bypass module verification. It was discovered that a buffer overflow existed in the trace subsystem in the Linux kernel. A privileged local attacker could use this to execute arbitrary code. Various other issues were also addressed.
