SNMP implementations and uncovered multiple problems which can
cause problems ranging from Denial of Service attacks to remote
exploits.

New UCD-SNMP packages have been prepared to fix these problems
as well as a few others. The complete list of fixed problems is:

  * When running external programs snmpd used temporary files insecurely

  * snmpd did not properly reset supplementary groups after changing
its uid and gid

  * Modified most code to use buffers instead of fixed-length strings to
prevent buffer overflows

  * The ASN.1 parser did not check for negative lengths

  * the IFINDEX response handling in snmpnetstat did not do a sanity check
on its input

(thanks to Caldera for most of the work on those patches)

The new version is 4.1.1-2.1 and we recommend you upgrade your
snmp packages immediately.");
