CVE-2017-1000111

CVE-2017-1000111 describes a heap/out-of-bounds race in the Linux kernel’s AF_PACKET socket handling (packet_set_ring) that can be exploited by a local user possessing CAP_NET_RAW to elevate privileges. The issue arises when a socket option changes socket state and races with safety checks; the r...

MGASA-2017-0279 Updated kernel packages fixes security and other bugs

This kernel update is based on upstream 4.4.82 and fixes at least the following security issues: The curseg-segno call in f2fs driver can be malformed so that it will have a value that triggers an out of boundary write that could cause memory corruption on the affected devices, leading to code...

UBUNTU-CVE-2017-1000111

Linux kernel: heap out-of-bounds in AFPACKET sockets. This new issue is analogous to previously disclosed CVE-2016-8655. In both cases, a socket option that changes socket state may race with safety checks in packetsetring. Previously with PACKETVERSION. This time with PACKETRESERVE. The solution...
