cryptography: PKCS#7 EnvelopedData decryption exposes a Bleichenbacher oracle through distinguishable errors and timing

Summarypkcs7decryptder, pkcs7decryptpem, and pkcs7decryptsmime reported theoutcome of decrypting a RecipientInfo's encryptedKey in severaldistinguishable ways, one of which disclosed the exact length recovered from theRSA operation. The same distinction was also observable by timing. Anapplicatio...

php: ext/openssl: memory corruption in openssl_encrypt with AES-WRAP-PAD

A flaw was found in the OpenSSL extension of PHP. The AES-WRAP-PAD algorithm implementation uses the size of the plaintext length without accounting for the RFC 5649 expansion to allocate the output buffer for the AES key-wrap-with-padding operation. This may lead to an undersized memory allocati...
