Summary
tomcat: Fix of 5 CVEs
Details
  • CVE-2026-55955: add replay protection to the cluster EncryptInterceptor by encrypting a trusted timestamp with each message and rejecting duplicate, stale or future messages via the new replayWindowTime and replayWindowMessageCount attributes (upstream tomcat 9.0.119). The default encryptionAlgorithm also changes from AES/CBC/PKCS5Padding to AES/GCM/NoPadding, because the replay protection is only effective for non-malleable algorithms. NOTE: this changes the encrypted cluster message format, so a cluster using EncryptInterceptor must be restarted as a whole, not node by node
