Unity Linux 20.1060e / 20.1070e Security Update: openssl (UTSA-2026-017581)

The Unity Linux 20 host has a package installed that is affected by a vulnerability as referenced in the UTSA-2026-017581 advisory. Calls to EVPCipherUpdate, EVPEncryptUpdate and EVPDecryptUpdate may overflow the output length argument in some cases where the input length is close to the maximum...

rust-openssl vulnerable to heap buffer overflow when encrypting with AES key-wrap-with-padding

CipherCtxRef::cipherupdate, CipherCtxRef::cipherupdatevec, and symm::Crypter::update incorrectly sized output buffers when used with AES key-wrap-with-padding ciphers EVPaes128,192,256wrappad. For a non-multiple-of-8 input, OpenSSL writes up to 7 bytes past the end of the caller's buffer or Vec,...

CipherCtxRef::cipherupdate, CipherCtxRef::cipherupdatevec, and symm::Crypter::update incorrectly sized output buffers when used with AES key-wrap-with-padding ciphers EVPaes128,192,256wrappad. For a non-multiple-of-8 input, OpenSSL writes up to 7 bytes past the end of the caller's buffer or Vec,...

JLSEC-2026-221 Integer Overflow in openssl-src

Calls to EVPCipherUpdate, EVPEncryptUpdate and EVPDecryptUpdate may overflow the output length argument in some cases where the input length is close to the maximum permissable length for an integer on the platform. In such cases the return value from the function call will be 1 indicating succes...

CVE-2022-40758

A Buffer Access with Incorrect Length Value vulnerablity in the TEECipherUpdate function in Samsung mTower through 0.3.0 allows a trusted application to trigger a Denial of Service DoS by invoking the function TEECipherUpdate with an excessive size value of srcLen...

The vulnerability of the Cipher.update_into function in the Python programming language-based cryptography interpreter allows a attacker to compromise the integrity and accessibility of the output data.

The vulnerability of the Cipher.updateinto function in the Python programming language’s cryptographic library is related to insufficient checking of unusual or exceptional states. Exploiting this vulnerability could allow a malicious actor to compromise the integrity and accessibility of the...
