========================================================================== Ubuntu Security Notice USN-3406-1 August 28, 2017
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 an out of bounds read vulnerability existed in the associative array implementation in the Linux kernel. A local attacker could use this to cause a denial of service (system crash) or expose sensitive information. (CVE-2016-7914)
It was discovered that a NULL pointer dereference existed in the Direct Rendering Manager (DRM) driver for VMWare devices in the Linux kernel. A local attacker could use this to cause a denial of service (system crash). (CVE-2017-7261)
It was discovered that the USB Cypress HID drivers for the Linux kernel did not properly validate reported information from the device. An attacker with physical access could use this to expose sensitive information (kernel memory). (CVE-2017-7273)
A reference count bug was discovered in the Linux kernel ipx protocol stack. A local attacker could exploit this flaw to cause a denial of service or possibly other unspecified problems. (CVE-2017-7487)
Huang Weller discovered that the ext4 filesystem implementation in the Linux kernel mishandled a needs-flushing-before-commit list. A local attacker could use this to expose sensitive information. (CVE-2017-7495)
It was discovered that an information leak existed in the set_mempolicy and mbind compat syscalls in the Linux kernel. A local attacker could use this to expose sensitive information (kernel memory). (CVE-2017-7616)
Update instructions:
The problem can be corrected by updating your system to the following package versions:
Ubuntu 14.04 LTS: linux-image-3.13.0-129-generic 3.13.0-129.178 linux-image-3.13.0-129-generic-lpae 3.13.0-129.178 linux-image-3.13.0-129-lowlatency 3.13.0-129.178 linux-image-3.13.0-129-powerpc-e500 3.13.0-129.178 linux-image-3.13.0-129-powerpc-e500mc 3.13.0-129.178 linux-image-3.13.0-129-powerpc-smp 3.13.0-129.178 linux-image-3.13.0-129-powerpc64-emb 3.13.0-129.178 linux-image-3.13.0-129-powerpc64-smp 3.13.0-129.178 linux-image-generic 3.13.0.129.138 linux-image-generic-lpae 3.13.0.129.138 linux-image-lowlatency 3.13.0.129.138 linux-image-powerpc-e500 3.13.0.129.138 linux-image-powerpc-e500mc 3.13.0.129.138 linux-image-powerpc-smp 3.13.0.129.138 linux-image-powerpc64-emb 3.13.0.129.138 linux-image-powerpc64-smp 3.13.0.129.138
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.
