========================================================================== Ubuntu Security Notice USN-3293-1 May 17, 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 kernel.
Software Description: - linux: Linux kernel - linux-raspi2: Linux kernel for Raspberry Pi 2
Details:
Dmitry Vyukov discovered that KVM implementation in the Linux kernel improperly emulated the VMXON instruction. A local attacker in a guest OS could use this to cause a denial of service (memory consumption) in the host OS. (CVE-2017-2596)
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)
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)
Li Qiang discovered that an integer overflow vulnerability 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) or possibly execute arbitrary code. (CVE-2017-7294)
Jason Donenfeld discovered a heap overflow in the MACsec module in the Linux kernel. An attacker could use this to cause a denial of service (system crash) or possibly execute arbitrary code. (CVE-2017-7477)
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 17.04: linux-image-4.10.0-1005-raspi2 4.10.0-1005.7 linux-image-4.10.0-21-generic 4.10.0-21.23 linux-image-4.10.0-21-generic-lpae 4.10.0-21.23 linux-image-4.10.0-21-lowlatency 4.10.0-21.23 linux-image-generic 4.10.0.21.23 linux-image-generic-lpae 4.10.0.21.23 linux-image-lowlatency 4.10.0.21.23 linux-image-raspi2 4.10.0.1005.7
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.
