A NULL pointer dereference in SANE Backends before 1.0.30 allows a malicious device connected to the same local network as the victim to cause a denial of service, GHSL-2020-079.

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'
