1. Problem Description

   Researchers at the university of Oulo, Finnland, discovered several
   remotely exploitable vulnerabilities in ucd-snmp. This security update
   fixes these vulnerabilities. This update also contains a patch from
   the SuSE security team that cleans up a number of unchecked memory
   operations.
