openssl: CMP indefinite cache growth of ExtraCerts

A flaw was found in OpenSSL. The CMP Certificate Management Protocol implementation does not clear cached additional certificates when an invalid message is received, leading to excessive memory consumption. This allows a malicious client to repeatedly send requests containing unique extra...

openssl: invalid pointer dereference in CMP server via crafted protectionAlg

A flaw was found in OpenSSL. A crafted CMP Certificate Management Protocol message can cause an invalid pointer dereference due to a missing type check in the password-based protection verification. A remote, unauthenticated attacker can crash applications acting as a CMP server or client,...

CVE-2026-63076

A flaw was found in OpenSSL. A crafted CMP Certificate Management Protocol message can cause an invalid pointer dereference due to a missing type check in the password-based protection verification. A remote, unauthenticated attacker can crash applications acting as a CMP server or client,...

CVE-2026-63074

Issue summary: The OpenSSL Certificate Management Protocol CMP caches additional certificates extraCerts sent in a CMP message, but never expunges them for instance if they are invalid. If a server reuses an OSSLCMPCTX frequently, this cache of extraCerts may grow unboundedly, and a malicious...

CVE-2026-63076

Issue summary: OpenSSL CMP password based protection verification only checks whether the protectionAlg parameter was not NULL and not its ASN.1 type, before treating it as a PBMParameter. A crafted message can contain a parameter of a different type, which is then dereferenced as an invalid...

CVE-2026-63073 Untrusted Sender DN Used as Format String in CMP Response Validation

Issue summary: OpenSSL CMP response validation passed an unexpected response sender distinguished name directly as the format string to ERRraisedata. Impact summary: A malicious or intercepted CMP endpoint can crash a CMP client that enforces an expected sender or uses a pinned server certificate...

Improper Verification of Cryptographic Signature

Overview Affected versions of this package are vulnerable to Improper Verification of Cryptographic Signature due to the verifybyte expected function in JcaContentVerifierProviderBuilder. An attacker can forge a protected CMP/PKI message by supplying an empty composite signature sequence that...
