========================================================================== Ubuntu Security Notice USN-3419-1 September 18, 2017
linux, linux-raspi2 vulnerabilities ==========================================================================
A security issue affects these releases of Ubuntu and its derivatives:
- Ubuntu 17.04
Summary:
Several security issues were fixed in the Linux kernel.
Software Description: - linux: Linux kernel - linux-raspi2: Linux kernel for Raspberry Pi 2
Details:
It was discovered that a buffer overflow existed in the Bluetooth stack of the Linux kernel when handling L2CAP configuration responses. A physically proximate attacker could use this to cause a denial of service (system crash). (CVE-2017-1000251)
It was discovered that a buffer overflow existed in the Broadcom FullMAC WLAN driver in the Linux kernel. A local attacker could use this to cause a denial of service (system crash) or possibly execute arbitrary code. (CVE-2017-7541)
Update instructions:
The problem can be corrected by updating your system to the following package versions:
Ubuntu 17.04: linux-image-4.10.0-1018-raspi2 4.10.0-1018.21 linux-image-4.10.0-35-generic 4.10.0-35.39 linux-image-4.10.0-35-generic-lpae 4.10.0-35.39 linux-image-4.10.0-35-lowlatency 4.10.0-35.39 linux-image-generic 4.10.0.35.35 linux-image-generic-lpae 4.10.0.35.35 linux-image-lowlatency 4.10.0.35.35 linux-image-raspi2 4.10.0.1018.19
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.
