Recommended response

  1. 1Check inventory. Check lockfiles and deployed manifests for Red Hat/clevis.
  2. 2Review the reported fix. Source-reported workaround: No end-user mitigation is available for this issue. The PIN exposure occurs in the clevis-decrypt-pkcs11 script itself, which must be updated to pass the PIN through an environment variable instead of the command line.

Sources and claim methodology

  • Source referencebugzilla.redhat.com
Upstream source description

A flaw was found in the clevis PKCS#11 pin. The clevis-decrypt-pkcs11 script passes the PKCS#11 token PIN as a command-line argument to pkcs11-tool, making it visible to any local user through process listing or the /proc filesystem.
