We have been contacted by CERT/CC about the following issue:
<quote>
According to net-snmp project:

"The quick technical summary is that the SNMPv3 packet contains a
truncated HMAC authentication code.  The author that wrote the code
very very long ago to check that HMAC code used the length of the
packet's version of the HMAC code to do the check.  Thus if you send a
single byte HMAC code, it'll only check it against the first byte of
HMAC output.  Thus it's fairly easy to spoof an authenticated SNMPv3
packet.

Thank you Matthias. Attached patch was corrupted one. Attaching correct one.

BTW, I don't see any rush with this security fix. I'm going to bump net-snmp
now to fix quite a number of bugs, after that I'd like to have at least 2 weeks
for feedback on patches I've backported from upstream and only after that
stabilize this package... Also we have another security fix for this package in
queue so it's better to test stabilize them together, I suppose.

Now public via URL.
"Fixed version:
Net-SNMP >= 5.4.1.1, >= 5.3.2.1, >= 5.2.4.1"

Peter, take the time you want to test this issue, 

5.4.1.1 is ready to go stable together with autoconf-2.61-r2 (which should be
stabilized in bug 227603).

Target keywords:
net-analyzer/net-snmp-5.4.1.1: alpha amd64 arm hppa ia64 ppc64 ppc s390 sh
sparc x86

x86 stable

pva, I'm adding release@, or did you handle this yourself already?

ppc64 stable

amd64 stable

alpha/ia64/sparc stable

Stable for HPPA.

ppc done

GLSA vote, YES for me.

YES too, filing request.

2008.0 is out, so no need to keep release on the CC list.
