Normally, CVE dupes are fairly straightforward, but it took some
coordination with Sun and Net-SNMP to find and address this dupe, and
a lot of vuln DB's may be affected.
See the analysis for CVE-2005-2177 below. It was even more painful
than it sounds ;-)

Reference: MLIST:[net-snmp-announce] 20050701 Multiple new Net-SNMP releases to fix a security related bug
Net-SNMP 5.0.x before 126.96.36.199, 5.2.x before 188.8.131.52, and 5.1.3, when
net-snmp is using stream sockets such as TCP, allows remote attackers
to cause a denial of service (daemon hang and CPU consumption) via a
TCP packet of length 1, which triggers an infinite loop.
ABSTRACTION: CVE-2006-5941 was flagged as a dupe of CVE-2005-2177 by
Net-SNMP and Sun in various e-mails from November 2006 to April 2007,
with the greatest clarification provided by Thomas Anders on Nov 30.
Summary: 1. the original description for CVE-2005-2177 was based on a
slightly vague disclosure by Net-SNMP; later information would show
that it deals with a length-1 TCP packet. 2. the NEWS file included
the same text in a "Security:" item for both 184.108.40.206 and 220.127.116.11,
but diff analysis had shown there were slightly different issues.
3. Sun requested CVE-2006-5941, since their information did not
exactly match their understanding of CVE-2005-2177. 4. After
publication of CVE-2006-5941, Net-SNMP and SuSE spotted the issue as a
potential dupe. 5. Further conversation with all parties made it
clear that Net-SNMP had fixed a separate issue, CVE-2005-4837, in a
similar version, but had not elevated it to "vulnerability" status.
CVE-2006-5941 was thus rejected.
snmp_api.c in snmpd in Net-SNMP 5.2.x before 5.2.2, 5.1.x before
5.1.3, and 5.0.x before 18.104.22.168, when running in master agentx mode,
allows remote attackers to cause a denial of service (crash) by
causing a particular TCP disconnect, which triggers a free of an
incorrect variable, a different vulnerability than CVE-2005-2177.
