Subject: [PATCH 2/7] Log if keyword is not properly separated
The man page states
Values are separated from directives by whitespace and/or an
optional =.
But logrotate does accept no separator, like
rotate7
Log those occurrences with a normal severity, as this usage is not
intended.

Subject: [PATCH 4/7] Fail on parse error of required option value
Fail on a parse error of a required option value of the directives
include, extension, addextension, rotate, start, minage, maxage,
shredcycles and su.
Failing is better than silently skipping a directive and running with an
undesired configuration.

sign
Do not warn if a configuration directive is specified with the key and
value separated by just an equal sign, like:
size=+2048k
The warning is intended for the usage of:
size2048k
Fixes: 2b588b5e ("Log if keyword is not properly separated")

Subject: [PATCH 6/7] config.c: enforce stricter parsing of config files
Abort parsing of config files that contain invalid lines.
This makes it harder to abuse logrotate for privilege escalation
attacks where an attacker can partially control a privileged file write.
