Created mingw-sane-backends tracking bugs for this issue: Affects: fedora-all [bug 1850558] Created sane-backends tracking bugs for this issue: Affects: fedora-all [bug 1850557] External References: https://gitlab.com/sane-project/backends/-/issues/279#issue-3-ghsl-2020-080-heap-buffer-overflow-in-epsonds_net_read This issue has been addressed in the following products: Red Hat Enterprise Linux 8 Via RHSA-2020:2902 https://access.redhat.com/errata/RHSA-2020:2902 This bug is now closed. Further updates for individual products will be reflected on the CVE page(s): https://access.redhat.com/security/cve/cve-2020-12861 This issue has been addressed in the following products: Red Hat Enterprise Linux 8.1 Extended Update Support Via RHSA-2020:2967 https://access.redhat.com/errata/RHSA-2020:2967 This issue has been addressed in the following products: Red Hat Enterprise Linux 8.0 Update Services for SAP Solutions Via RHSA-2020:3045 https://access.redhat.com/errata/RHSA-2020:3045 Statement: The vulnerable code is a part of "driver for Epson ESC/I-2 scanners" which was first introduced in sane-backends-1.0.25 (via https://gitlab.com/sane-project/backends/-/commit/d72f4663c0ad6e6f779c15c8baf5f92b675ae19a). Therefore, only versions of sane-backends shipped with Red Hat Enterprise Linux 8 are affected by this flaw. Mitigation: This flaw can be mitigated by limiting network scanner discovery to a trusted subnet via the "net" configuration in the "/etc/sane.d/epsonds.conf" configuration file. Also, automatic network scanner discovery can be turned off by commenting out the line "net autodiscovery" in the same configuration file. |
