This update was imported from the SUSE:SLE-15:Update update project.

A regression was introduced in DLA-2332-1, where changes in the Debian package building process triggered a bug in the sane-backends packages, causing missing files.

For Debian 9 stretch, this problem has been fixed in version 1.0.25-4.1+deb9u2.

We recommend that you upgrade your sane-backends packages.

New sane packages are available for Slackware 14.0, 14.1, 14.2, and
-current to fix security issues.

The remote Ubuntu 16.04 LTS / 18.04 LTS / 20.04 LTS host has packages installed that are affected by multiple vulnerabilities as referenced in the USN-4470-1 advisory.

    Kritphong Mongkhonvanit discovered that sane-backends incorrectly handled certain packets. A remote     attacker could possibly use this issue to obtain sensitive memory information. This issue only affected     Ubuntu 16.04 LTS. (CVE-2017-6318)

    It was discovered that sane-backends incorrectly handled certain memory operations. A remote attacker     could possibly use this issue to execute arbitrary code. This issue only applied to Ubuntu 18.04 LTS and     Ubuntu 20.04 LTS. (CVE-2020-12861)

    It was discovered that sane-backends incorrectly handled certain memory operations. A remote attacker     could possibly use this issue to obtain sensitive information. (CVE-2020-12862, CVE-2020-12863)

    It was discovered that sane-backends incorrectly handled certain memory operations. A remote attacker     could possibly use this issue to execute arbitrary code. (CVE-2020-12865)

    It was discovered that sane-backends incorrectly handled certain memory operations. A remote attacker     could possibly use this issue to cause a denial of service. This issue only applied to Ubuntu 18.04 LTS     and Ubuntu 20.04 LTS. (CVE-2020-12866)

    It was discovered that sane-backends incorrectly handled certain memory operations. A remote attacker     could possibly use this issue to cause a denial of service. (CVE-2020-12867)

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

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'

According to the versions of the sane-backends packages installed, the EulerOS installation on the remote host is affected by the following vulnerabilities :

  - An out-of-bounds read in SANE Backends before 1.0.30 may allow a malicious device connected to the same     local network as the victim to read important information, such as the ASLR offsets of the program, aka     GHSL-2020-082. (CVE-2020-12862)

  - An out-of-bounds read in SANE Backends before 1.0.30 may allow a malicious device connected to the same     local network as the victim to read important information, such as the ASLR offsets of the program, aka     GHSL-2020-083. (CVE-2020-12863)

  - A NULL pointer dereference in sanei_epson_net_read 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, aka GHSL-2020-075.
    (CVE-2020-12867)
