Description Josh Bressers 2005-07-11 16:19:25 UTC

+++ This bug was initially created as a clone of Bug #162907 +++

This text comes from this message:
http://sourceforge.net/mailarchive/forum.php?thread_id=7659656&forum_id=12455
From: Wes Hardaker

 A security vulnerability has been found in Net-SNMP releases that
 could allow a denial of service attack against Net-SNMP agent"s which
 have opened a stream based protocol (EG, TCP but not UDP; it should be
 noted that Net-SNMP does not by default open a TCP port).  Because of
 this, we"ve immediately released a number of Net-SNMP versions
 (5.2.1.2, 5.1.3, and 5.0.10.2) to fix this problem in the various
 Net-SNMP branches.  Most of these versions are minor patches from a
 previous release, but since we were so close to releasing 5.1.3 anyway
 we decided to do a full release of that rather than an incremental
 release from the 5.1.2 release.



While this issue is for net-snmp, ucd-snmp shares much of the same code.  I
don't know yet if this affects ucd-snmp.

Will investigate.

Read ya, Phil

Comment 2 Phil Knirsch 2005-08-03 15:55:52 UTC

Reviewed the fix today and found the actual security fix.

Backported the relevant fixes back to ucd-snmp and built a package for RHEL-2.1

Please open an errata at your convenience.

Thanks,

Read ya, Phil
