CESS

CESS — क्रिप्टोलॉजिकल रूप से मंत्रमुग्ध शमीर का सीक्रेट क्या यह AI बकवास या घटिया है? CESS की समीक्षा करने वाला कोई क्रिप्टोग्राफर या गंभीर कार्यान्वयनकर्ता आमतौर पर गद्य पढ़ने से पहले vectors/ और testdata/ खोलेगा। परीक्षण सुइट कार्य का प्रमाण है: यह डोमेन ज्ञान को कूटबद्ध करता है जिसे केवल वर्णन...

EUVD-2026-65488

Issue summary: ChaCha20-Poly1305 and AES-OCB decryption with an empty ciphertext can report success without verifying the supplied authentication tag when the operation is finalized by calling the EVPCipher function. Impact summary: Applications calling EVPCipher on an empty ciphertext and...

CVE-2026-75803

OpenSSL's EVP_Cipher() API, when used as a one-shot decryption call for ChaCha20-Poly1305 and AES-OCB ciphers, skips the AEAD authentication tag verification if the input ciphertext is empty. A successful return value in that case does not guarantee the tag was actually validated, so applications...

CVE-2026-75803 AEAD Forgeries with Empty Ciphertext When Using EVP_Cipher()

Issue summary: ChaCha20-Poly1305 and AES-OCB decryption with an empty ciphertext can report success without verifying the supplied authentication tag when the operation is finalized by calling the EVPCipher function. Impact summary: Applications calling EVPCipher on an empty ciphertext and...

CVE-2026-64314 crypto: chacha20poly1305 - validate poly1305 template argument

In the Linux kernel, the following vulnerability has been resolved: crypto: chacha20poly1305 - validate poly1305 template argument chachapolycreate still accepts the compatibility poly1305 parameter in the template name, but it assumes the second template argument is always present and immediatel...

JLSEC-2026-728 In wolfSSL's EVP layer, the ChaCha20-Poly1305 AEAD decryption path in `wolfSSL_EVP_CipherFinal` (and...

In wolfSSL's EVP layer, the ChaCha20-Poly1305 AEAD decryption path in wolfSSLEVPCipherFinal and related EVP cipher finalization functions fails to verify the authentication tag before returning plaintext to the caller. When an application uses the EVP API to perform ChaCha20-Poly1305 decryption,...

Prefix Truncation Attack against ChaCha20-Poly1305 and Encrypt-then-MAC aka Terrapin

SummaryTerrapin is a prefix truncation attack targeting the SSH protocol. More precisely, Terrapin breaks the integrity of SSH's secure channel. By carefully adjusting the sequence numbers during the handshake, an attacker can remove an arbitrary amount of messages sent by the client or server at...

DEBIAN-CVE-2026-13758

CryptX versions before 0.088001 for Perl compare AEAD authentication tags in non-constant time in the streaming decryptdone path. The decryptdone$tag form compares it against the computed tag with memNE memcmp != 0, which short-circuits on the first differing byte, so its run time depends on the...

GHSA-6VVH-PXR4-25R7 PHP JWT Framework: Chacha20Poly1305 key-encryption algorithm discards the Poly1305 authentication tag, performing no authentication on decryption

Impact The experimental Chacha20Poly1305 key-encryption algorithm generates the 16-byte Poly1305 authentication tag during encryptKey but discards it: the tag is never written to the header and therefore never reaches the wire. On the receiving side, decryptKey calls...

CVE-2026-41565

CryptX versions before 0.088001 for Perl have a stack buffer overflow in four AEAD decryptverify helpers. The gcmdecryptverify, ccmdecryptverify, chacha20poly1305decryptverify and eaxdecryptverify XS routines copied the caller-supplied authentication tag into a fixed 144-byte stack buffer...

Astra Linux – Vulnerability in nss

A flaw was discovered in the implementation of CHACHA20-POLY1305 in NSS versions prior to 3.55. When using multi-part Chacha20, it could lead to out-of-bounds reads. This issue was addressed by explicitly disabling multi-part ChaCha20 which was not functioning correctly and enforcing strict tag...
