> If an ACL is misconfigured in the realtime database (for instance, the "rule" is blank) and Asterisk attempts to read the ACL, asterisk will segfault during reading the rule and crash. For some reason it doesn't seem to produce a coredump, however I haven't verified that this isn't because my system is incorrectly configured.
> This can be worked around by ensuring the ACLs are not misconfigured, but ideally asterisk should gracefully fail and not crash.
