Detail
| A security issue affects these releases of Ubuntu and its derivatives: - Ubuntu 17.10 Summary: Several security issues were fixed in the Linux kernel. Software Description: - linux-raspi2: Linux kernel for Raspberry Pi 2 Details: Jann Horn discovered that the Berkeley Packet Filter (BPF) implementation in the Linux kernel did not properly check the relationship between pointer values and the BPF stack. A local attacker could use this to cause a denial of service (system crash) or possibly execute arbitrary code. (CVE-2017-17863) Jann Horn discovered that the Berkeley Packet Filter (BPF) implementation in the Linux kernel improperly performed sign extension in some situations. A local attacker could use this to cause a denial of service (system crash) or possibly execute arbitrary code. (CVE-2017-16995) Alexei Starovoitov discovered that the Berkeley Packet Filter (BPF) implementation in the Linux kernel contained a branch-pruning logic issue around unreachable code. A local attacker could use this to cause a denial of service. (CVE-2017-17862) Jann Horn discovered that the Berkeley Packet Filter (BPF) implementation in the Linux kernel mishandled pointer data values in some situations. A local attacker could use this to to expose sensitive information (kernel memory). (CVE-2017-17864) Update instructions: The problem can be corrected by updating your system to the following package versions: Ubuntu 17.10: 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.
