"This update for sane-backends fixes the following issues :

sane-backends version upgrade to 1.0.31 :

  - sane-backends version upgrade to 1.0.30 fixes memory
    corruption bugs CVE-2020-12861, CVE-2020-12862,
    CVE-2020-12863, CVE-2020-12864, CVE-2020-12865,
    CVE-2020-12866, CVE-2020-12867 (bsc#1172524)

  - sane-backends version upgrade to 1.0.31 to further
    improve hardware enablement for scanner devices
    (jsc#SLE-15561 and jsc#SLE-15560 with jsc#ECO-2418)

  - The new escl backend cannot be provided for SLE12
    because it requires more additional software
    (avahi-client, libcurl, and libpoppler-glib-devel) where
    in particular for libcurl the one that is in SLE12 (via
    libcurl-devel-7.37.0) is likely too old because with
    that building the escl backend fails with
    'escl/escl.c:1267:34: error: 'CURLOPT_UNIX_SOCKET_PATH'
    undeclared curl_easy_setopt(handle,
    CURLOPT_UNIX_SOCKET_PATH'

Note that Tenable Network Security has extracted the preceding
description block directly from the SUSE security advisory. Tenable
has attempted to automatically clean and format it as much as possible
without introducing additional issues.");
