Debian Security Advisory DSA-111-1 security@debian.org http://www.debian.org/security/ Wichert Akkerman February 14, 2002


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.

wget url will fetch the file for you dpkg -i file.deb will install the referenced file.

Debian GNU/Linux 2.2 alias potato
