========================================================================== Ubuntu Security Notice USN-3620-1 April 04, 2018
linux vulnerabilities ==========================================================================
A security issue affects these releases of Ubuntu and its derivatives:
- Ubuntu 14.04 LTS
Summary:
Several security issues were fixed in the Linux kernel.
Software Description: - linux: Linux kernel
Details:
It was discovered that the netlink 802.11 configuration interface in the Linux kernel did not properly validate some attributes passed from userspace. A local attacker with the CAP_NET_ADMIN privilege could use this to cause a denial of service (system crash) or possibly execute arbitrary code. (CVE-2017-11089)
It was discovered that a buffer overflow existed in the ioctl handling code in the ISDN subsystem of the Linux kernel. A local attacker could use this to cause a denial of service (system crash) or possibly execute arbitrary code. (CVE-2017-12762)
It was discovered that the netfilter component of the Linux did not properly restrict access to the connection tracking helpers list. A local attacker could use this to bypass intended access restrictions. (CVE-2017-17448)
Dmitry Vyukov discovered that the KVM implementation in the Linux kernel contained an out-of-bounds read when handling memory-mapped I/O. A local attacker could use this to expose sensitive information. (CVE-2017-17741)
It was discovered that the Salsa20 encryption algorithm implementations in the Linux kernel did not properly handle zero-length inputs. A local attacker could use this to cause a denial of service (system crash). (CVE-2017-17805)
It was discovered that the keyring implementation in the Linux kernel did not properly check permissions when a key request was performed on a task's' default keyring. A local attacker could use this to add keys to unauthorized keyrings. (CVE-2017-17807)
It was discovered that the Broadcom NetXtremeII ethernet driver in the Linux kernel did not properly validate Generic Segment Offload (GSO) packet sizes. An attacker could use this to cause a denial of service (interface unavailability). (CVE-2018-1000026)
It was discovered that the Reliable Datagram Socket (RDS) implementation in the Linux kernel contained an out-of-bounds write during RDMA page allocation. An attacker could use this to cause a denial of service (system crash) or possibly execute arbitrary code. (CVE-2018-5332)
Update instructions:
The problem can be corrected by updating your system to the following package versions:
Ubuntu 14.04 LTS: linux-image-3.13.0-144-generic 3.13.0-144.193 linux-image-3.13.0-144-generic-lpae 3.13.0-144.193 linux-image-3.13.0-144-lowlatency 3.13.0-144.193 linux-image-3.13.0-144-powerpc-e500 3.13.0-144.193 linux-image-3.13.0-144-powerpc-e500mc 3.13.0-144.193 linux-image-3.13.0-144-powerpc-smp 3.13.0-144.193 linux-image-3.13.0-144-powerpc64-emb 3.13.0-144.193 linux-image-3.13.0-144-powerpc64-smp 3.13.0-144.193 linux-image-generic 3.13.0.144.154 linux-image-generic-lpae 3.13.0.144.154 linux-image-lowlatency 3.13.0.144.154 linux-image-powerpc-e500 3.13.0.144.154 linux-image-powerpc-e500mc 3.13.0.144.154 linux-image-powerpc-smp 3.13.0.144.154 linux-image-powerpc64-emb 3.13.0.144.154 linux-image-powerpc64-smp 3.13.0.144.154
After a standard system update you need to reboot your computer to make all the necessary changes.
ATTENTION: Due to an unavoidable ABI change the kernel updates have been given a new version number, which requires you to recompile and reinstall all third party kernel modules you might have installed. Unless you manually uninstalled the standard kernel metapackages (e.g. linux-generic, linux-generic-lts-RELEASE, linux-virtual, linux-powerpc), a standard system upgrade will automatically perform this as well.
