CVSS v3.1 |
| libspdm is a sample implementation that follows the DMTF SPDM specifications. In version 1.4.0, both the FINISH request (Table 80) and the FINISH_RSP response (Table 81) gained two new fields, OpaqueDataLength and OpaqueData, placed before the trailing signed/authenticated field. The transcript definitions used to compute and verify the FINISH signature, the FINISH HMAC (RequesterVerifyData), and the FINISH_RSP HMAC (ResponderVerifyData) were not updated and still terminate with a step of the form. Per DSP0274, the "SPDM Header Fields" are only the four header bytes (SPDMVersion, RequestResponseCode, Param1, Param2). A literal reading therefore excludes OpaqueDataLength and OpaqueData, even though those fields are transmitted before the trailing signature/HMAC field. Because the signature/HMAC must cover every field transmitted before it to "protect the entire handshake against manipulation by an active attacker," an active attacker could otherwise modify the opaque data in flight without invalidating the signature or HMAC. This issue has been patched in version 1.4.1. |
| Missing cryptographic step in Windows CryptoAPI allows an authorized attacker to perform tampering locally. |
| Issue summary: The AES-GCM-SIV implementation treats a zero-length Additional
Authenticated Data (AAD) update as a reset of all the AAD supplied so far,
instead of leaving the AAD unchanged. An application that supplies its AAD in
several fragments, one of which is empty, therefore produces or verifies
messages whose authentication tag does not cover the AAD supplied before
the empty fragment.
Impact summary: Data an application intended to authenticate alongside a
message is silently left unauthenticated. An attacker can forge the AAD of such
a message.
CWE: CWE-325: Missing Cryptographic Step
Description: An application passing AAD in multiple chunks of which some have
zero length will have the previous AAD chunks effectively unauthenticated. Also,
on context re-initialisation, the AAD was not reset, which meant that any AAD
accumulated from the previous context usage were also included in the AAD of the
new message.
The fix makes a zero-length AAD update a no-op and clears any accumulated AAD
whenever the context is re-initialised with a key or a nonce.
A re-initialisation that only changes parameters keeps the AAD.
FIPS impact: no
The FIPS modules are not affected, as AES-GCM-SIV is not a FIPS approved
algorithm and is implemented only in the default provider, outside the
OpenSSL FIPS module boundary. |
| IBM Db2 Genius Hub 1.1.2, 1.1.3, 1.1.4, 1.1.5 could allow a remote authenticated attacker to obtain sensitive information due to missing required cryptographic step. |
| Cryptographic issue in the WebRTC: Networking component. This vulnerability was fixed in Firefox 159, Firefox ESR 153.6, Thunderbird 159, and Thunderbird 153.6. |
| Forge (also called node-forge) is a native implementation of Transport Layer Security in JavaScript. Prior to 1.4.1, the affected implementation used decipher.finish(), CBC and ECB modes, PKCS#7 padding to process the relevant input or security decision. node-forge validated only the final byte of PKCS#7 padding during CBC and ECB decryption and accepted zero, oversized, or mismatched padding bytes. Malformed ciphertext could consequently be accepted and up to four plaintext blocks could be silently removed, causing an integrity failure in applications that treated successful decryption as proof of valid padding. This issue is fixed in version 1.4.1. |
| Missing cryptographic step in the DSTU 7624 CCM mode implementation (KCcmBlockCipher) in Legion of the Bouncy Castle Inc. bc-csharp before 2.7.0 allows an attacker who can observe encrypted messages of known or chosen content to forge ciphertexts with valid authentication tags, via messages encrypted without associated data. The cause is that the G1 block, which binds the nonce, the message length and the parameter flags into the CBC-MAC, was processed only when associated data was present. Without associated data the tag was a CBC-MAC of the plaintext alone, independent of the nonce. Only applications that use KCcmBlockCipher directly and supply no associated data are affected. |
| In the Linux kernel, the following vulnerability has been resolved:
crypto: krb5enc - fix async decrypt skipping hash verification
krb5enc_dispatch_decrypt() sets req->base.complete as the skcipher
callback, which is the caller's own completion handler. When the
skcipher completes asynchronously, this signals "done" to the caller
without executing krb5enc_dispatch_decrypt_hash(), completely bypassing
the integrity verification (hash check).
Compare with the encrypt path which correctly uses
krb5enc_encrypt_done as an intermediate callback to chain into the
hash computation on async completion.
Fix by adding krb5enc_decrypt_done as an intermediate callback that
chains into krb5enc_dispatch_decrypt_hash() upon async skcipher
completion, matching the encrypt path's callback pattern.
Also fix EBUSY/EINPROGRESS handling throughout: remove
krb5enc_request_complete() which incorrectly swallowed EINPROGRESS
notifications that must be passed up to callers waiting on backlogged
requests, and add missing EBUSY checks in krb5enc_encrypt_ahash_done
for the dispatch_encrypt return value.
Unset MAY_BACKLOG on the async completion path so the user won't
see back-to-back EINPROGRESS notifications. |
| Cryptography misuse in Storage: Quota Manager component. This vulnerability was fixed in Firefox ESR 153.4, Thunderbird 157, Thunderbird 153.4, and Firefox 157. |
| IBM Db2 Genius Hub 1.0 could allow a remote authenticated attacker to bypass security restrictions due to a missing initialization vector in the cryptographic algorithm. |
| Using its HSTS support, curl can be instructed to use HTTPS directly insteadof using an insecure clear-text HTTP step even when HTTP is provided in theURL. This mechanism could be bypassed if the host name in the given URL used atrailing dot while not using one when it built the HSTS cache. Or the otherway around - by having the trailing dot in the HSTS cache and *not* using thetrailing dot in the URL. |
| IBM WebSphere Application Server - Liberty 17.0.0.3 through 26.0.0.10 and IBM WebSphere Application Server 8.5, and 9.0 could allow a remote attacker to bypass cryptographic signature verification due to improper verification of cryptographic signature. |
| AES OCB mode for 32-bit x86 platforms using the AES-NI assembly optimised implementation will not encrypt the entirety of the data under some circumstances. This could reveal sixteen bytes of data that was preexisting in the memory that wasn't written. In the special case of "in place" encryption, sixteen bytes of the plaintext would be revealed. Since OpenSSL does not support OCB based cipher suites for TLS and DTLS, they are both unaffected. Fixed in OpenSSL 3.0.5 (Affected 3.0.0-3.0.4). Fixed in OpenSSL 1.1.1q (Affected 1.1.1-1.1.1p). |
| Libgcrypt before 1.8.8 and 1.9.x before 1.9.3 mishandles ElGamal encryption because it lacks exponent blinding to address a side-channel attack against mpi_powm, and the window size is not chosen appropriately. This, for example, affects use of ElGamal in OpenPGP. |
| A user can tell curl >= 7.20.0 and <= 7.78.0 to require a successful upgrade to TLS when speaking to an IMAP, POP3 or FTP server (`--ssl-reqd` on the command line or`CURLOPT_USE_SSL` set to `CURLUSESSL_CONTROL` or `CURLUSESSL_ALL` withlibcurl). This requirement could be bypassed if the server would return a properly crafted but perfectly legitimate response.This flaw would then make curl silently continue its operations **withoutTLS** contrary to the instructions and expectations, exposing possibly sensitive data in clear text over the network. |
| Crux Agent from 1.9.0 before 2.0.3 uses the full SKA bilocation key as the WireGuard preshared key. When a peering session negotiates use of SHA-512, the key produced is 64 bytes instead of the 32 bytes WireGuard requires. The agent does not validate this size; instead it attempts to use the `wg set` command to update the live tunnel, and write the invalid key to the WireGuard configuration file. The update fails, so the live tunnel keeps using its previous preshared key until the tunnel is shut down. The tunnel will fail to start when restarted.
For a peer which has never successfully negotiated a 32-byte bilocation key in a Crux C2 organization which has the "Enforce SKA Use" setting turned off, no preshared key will be set for the tunnel. Therefore, an attacker who is able to intercept and store the peer's traffic, and has access (or will have access) to a cryptographically relevant quantum computer, will be able to decrypt the tunnel. |
| During key agreement in a TLS handshake using a DH(E) based ciphersuite a malicious server can send a very large prime value to the client. This will cause the client to spend an unreasonably long period of time generating a key for this prime resulting in a hang until the client has finished. This could be exploited in a Denial Of Service attack. Fixed in OpenSSL 1.1.0i-dev (Affected 1.1.0-1.1.0h). Fixed in OpenSSL 1.0.2p-dev (Affected 1.0.2-1.0.2o). |
