Intresting problem concerning libresolv.so.2

From: Sam Evans (samneuroflux.com)

I've run into an interesting dilema with a machine that's running Solaris
8.. It would appear as if the /usr/lib/libresolv.so.2 file changed, but
didn't really change..

What I mean is this.. We run Tripwire on this box, and Tripwire reported
that the hash sums were different than what it expected. Everything else
was the same (timestamps, inode, block values, etc). This would indicate
that the contents changed inside the file..

What's also interesting is that this is the *only* file that was listed in
the tripwire report for the day. Nothing else changed (at least according
to Tripwire).

Anyone have any thoughts on this? For what it's worth the box does run
sendmail, and was patched for the March vulnerability, but not the April
vulnerability.

Thanks,
Sam
