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.

It was discovered that the keyring implementation in the Linux kernel did
not properly restrict searches for dead keys. A local attacker could use
this to cause a denial of service (system crash). (CVE-2017-6951)
Dmitry Vyukov discovered that the generic SCSI (sg) subsystem in the Linux
kernel contained a stack-based buffer overflow. A local attacker with
access to an sg device could use this to cause a denial of service (system
crash) or possibly execute arbitrary code. (CVE-2017-7187)
Eric Biggers discovered a memory leak in the keyring implementation in the
Linux kernel. A local attacker could use this to cause a denial of service
(memory consumption). (CVE-2017-7472)
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 12.04 ESM:
linux-image-3.13.0-132-generic 3.13.0-132.181~precise1
linux-image-3.13.0-132-generic-lpae 3.13.0-132.181~precise1
linux-image-generic-lpae-lts-trusty 3.13.0.132.122
linux-image-generic-lts-trusty 3.13.0.132.122
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.
