USN-3674-1

Summary: linux vulnerabilities

Details: It was discovered that the netfilter subsystem of the Linux kernel did not properly validate ebtables offsets. A local attacker could use this to cause a denial of service (system crash) or possibly execute arbitrary code. (CVE-2018-1068) It was discovered that a NULL pointer dereference existed in the RDS (Reliable Datagram Sockets) protocol implementation in the Linux kernel. A local attacker could use this to cause a denial of service (system crash). (CVE-2018-7492) Eyal Itkin discovered that the USB displaylink video adapter driver in the Linux kernel did not properly validate mmap offsets sent from userspace. A local attacker could use this to expose sensitive information (kernel memory) or possibly execute arbitrary code. (CVE-2018-8781) Xingyuan Lin discovered that a out-of-bounds read existed in the USB Video Class (UVC) driver of the Linux kernel. A local attacker could use this to expose sensitive information (kernel memory). (CVE-2017-0627)
