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.
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.
