Comment 1 Oliver Bassett 2003-01-23 02:15:08 UTC
This issue was fixed in Revision 5.15 in the Net-SNMP CVS.

Revision 5.15 </cgi-bin/viewcvs.cgi/*checkout*/net-snmp/net-
snmp/snmplib/snmp_api.c?rev=5.15> / (view) <snmp_api.c?rev=5.15&content-
type=text/vnd.viewcvs-markup> - annotate <snmp_api.c?annotate=5.15> - [select 
for diffs] <snmp_api.c?r1=5.15> , Mon Sep 9 13:28:40 2002 UTC (4 months, 1 week 
ago) by jbpn 
Branch: MAIN <snmp_api.c?only_with_tag=MAIN> 
Changes since 5.14: +7 -4 lines 
Diff to previous 5.14 <snmp_api.c.diff?r1=5.14&r2=5.15> 
  - fix bug pointed out by Jared Smith-Mickelson (bug #605147)
    whereby passing an unknown type character to snmp_add_var would
    cause a segfault.

Comment 2 Phil Knirsch 2003-02-05 17:47:40 UTC
Seems to be fixed in the latest rawhide release.

I've run the snmptrap command and snmpd didn't segfault.

Read ya, Phil
