• [SECURITY] [DSA 4073-1] linux security update (2/2)

    From Ben Hutchings@1:229/2 to All on Sat Dec 23 21:20:02 2017
    [continued from previous message]

    The various problems in the Extended BPF verifier can be mitigated by
    disabling use of Extended BPF by unprivileged users:
    sysctl kernel.unprivileged_bpf_disabled=1

    Debian disables unprivileged user namespaces by default, but if they
    are enabled (via the kernel.unprivileged_userns_clone sysctl) then CVE-2017-17448 can be exploited by any local user.

    For the stable distribution (stretch), these problems have been fixed in version 4.9.65-3+deb9u1.

    We recommend that you upgrade your linux packages.

    For the detailed security status of linux please refer to its security
    tracker page at: https://security-tracker.debian.org/tracker/linux

    these updates to your system and frequently asked questions can be
