I noticed that whenever I use an override in my snmpd.conf file, I get a core
dump. I compiled net-snmp-5.1.1 on slackware 9.1.
For example:
override sysDescr.0 octet_str "foo"
will cause the daemon to toss core while it is parsing the config file.
The problem is in agent_registry.c, line 566:
subtree->label_a = strdup(moduleName);
In this case, moduleName is NULL. strdup() will throw core when it gets a NULL.
I found that the following band-aid:
subtree->label_a = (moduleName == NULL) ? strdup("") : strdup(moduleName);
will fix it up.
I see the same code in 5.0.9 where it didn't cause problems. Presumably
moduleName wasn't NULL.
There is probably a better way to fix this, maybe by producing a legitimate
string in the override code but I don't know what a legitimate string would be.
Anybody else seen this?
If there's anything else I can do to help, please let me know.
