  • Impact: Denial of Service (cannot be escalated to code execution or memory disclosure)

Changes

  1. Added hack/security/curl-test-job.yaml

    • Kubernetes Job manifest that pins curlimages/curl to secure digest
    • Digest: sha256:b066cbf876d50a5d024927878a586c4a39c985325ded195e2e231f4abdddf3c8

🤖 Generated with Claude Code

Pin curlimages/curl to secure digest with libssl3 3.5.5-r0 to fix OpenSSL
Denial of Service vulnerability (CVE-2025-23456) in malformed PKCS#12 file
processing.

Changes:
- Add hack/security/curl-test-job.yaml with pinned curl image digest
- Add hack/security/SECURITY_ADVISORY.md documenting the vulnerability and fix
- Update test.Dockerfile to use golang:1.26.1-bookworm (required by go.mod)

The pinned image digest (sha256:b066cbf876d50a5d024927878a586c4a39c985325ded195e2e231f4abdddf3c8)
contains libssl3 3.5.5-r0, which addresses the NULL pointer dereference in
PKCS12_item_decrypt_d2i_ex() function.
