This bug is still present on 5.5. An attempt to write a file system abstraction layer (agent/mibgroup/hardware/fsys/) was started back in 2008 and I suppose one of the motivations was to fix this problem. Unfortunately that effort seems to be on hold for a while, so I wonder if anyone can see another way to fix or workaround this problem.

oops, 17861 is the SVN revision number with the fix, 17719 is the one which introduced the bug :)

Thanks for the bug report!
We've fixed the problem in the 5.5.x code branch
and the main development tree, so it should be
fixed in future releases of the Net-SNMP package.

I've already fixed it some time ago in SVN rev. 17719.

I cannot reproduce this issue with any other Linux distro, so the Fedora Rawhide maintainers should have a look at this first. Please log this into the RedHat bugzilla and post the URL of the RedHat bugzilla entry here.

'.fc13' means it's Fedora Rawhide. And looking at snmpwalk output there, I get following values (each with different snmpwalk):
TCP-MIB::tcpListenerProcess.ipv4."0.0.0.0".22 = Gauge32: 2688009616
TCP-MIB::tcpListenerProcess.ipv4."0.0.0.0".22 = Gauge32: 147456
TCP-MIB::tcpListenerProcess.ipv4."0.0.0.0".22 = Gauge32: 49
TCP-MIB::tcpListenerProcess.ipv4."0.0.0.0".22 = Gauge32: 16384...

I just had a look at source code file
net-snmp-5.4.2.1/agent/mibgroup/hardware/cpu/cpu_kstat.c,
around line 60 is code
state[sizeof(ctype)-1] = '\0';
but
char ctype[15], ftype[15], state[10];
so there is an index of 14 into an array of size 10. Suggest code rework.
A little later in the same file is the same problem again.
