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

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.
