sane-backends: Reading uninitialized data in epsonds_net_read in epsonds-net.c
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-2020-081.
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 is 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"
