Package: libsane
Version: 1.0.24-8
Severity: important
Dear Maintainer,
Using the artec_eplus48u backend (via network in my case) crashes saned.
I was able to capture the following backtrace:
#0 __strlen_sse2 () at ../sysdeps/i386/i686/multiarch/strlen-sse2.S:62
#1 0xb60205b9 in load_calibration_data (s=0xb5461008) at

The code in question (artec_eplus48.c around line 3583):
[... load_calibration_data() ...]
s-calibrated = SANE_FALSE;
path[0] = 0;
if (strlen (getenv (HOME)) (PATH_MAX - 1))
strcat (path, getenv (HOME));
else
return SANE_STATUS_INVAL
[...]
Because saned, as started by systemd, does not have the HOME varible in its
environment,
getenv(HOME) returns 0 and strlen crashes. This can be verified by
setting HOME in the init script: saned no longer crashes and scanning
works fine.
Hope this helps,
Alex
