CVE-2011-4190 — Suse Suse Linux Enterprise Desktop security vulnerability

Medium CVSS 5.9

The kdump implementation is missing the host key verification in the kdump and mkdumprd OpenSSH integration of kdump prior to version 2012-01-20. This is similar to CVE-2011-3588, but different in that the kdump implementation is specific to SUSE. A remote malicious kdump server could use this flaw to impersonate the correct kdump server to obtain security sensitive information (kdump core files).

Authentication bypass and missing authentication

This catalog composition supplies bounded fallback guidance. Explicitly reviewed curated workflows load with the complete record below.

Check exposure

  • Map every affected endpoint and protocol path, including alternate ports, legacy routes, recovery flows, service accounts, and machine-to-machine access.
  • Confirm which deployments enable the affected authentication mode and whether the interface is reachable from untrusted networks.
  • Review session, token, credential, and proxy trust configuration without attempting account takeover.

Remediate safely

  • Apply the supported fix and centralize fail-closed authentication before protected request handling.
  • Remove default or embedded credentials, rotate affected secrets and sessions, and bind authentication decisions to the intended audience and channel.
  • Add negative tests for alternate routes, malformed or absent credentials, recovery flows, and proxy-derived identity.
