Subject:                Linux - security issues in ucd-snmp
Advisory number:        CSSA-2001-031.0
Issue date:             2001, August 16

1. Problem Description

   In a routine security audit of the ucd-snmp package we have found
   several problems, including several potentially exploitable buffer
   overflows, format string bugs, signedness issues and tempfile race
   conditions. Some of these might allow remote attackers to gain access
   to the UID under which snmpd is running. This update fixes all known
   problems and also makes the snmpd run as user 'nobody', reducing the
   impact of further problems.
