Debian Security Advisory DSA-111-1                   security@debian.org

Package        : ucd-snmp
Problem type   : remote exploit
Debian-specific: no
CERT Advisory  : CA-2002-03

The Secure Programming Group of the Oulu University did a study on
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.
