openssl: use-after-free following BIO_new_NDEF

A use-after-free vulnerability was found in OpenSSL's BIOnewNDEF function. The public API function BIOnewNDEF is a helper function used for streaming ASN.1 data via a BIO. It is primarily used internally by OpenSSL to support the SMIME, CMS, and PKCS7 streaming capabilities, but it may also be...

openssl: double free after calling PEM_read_bio_ex

A double-free vulnerability was found in OpenSSL's PEMreadbioex function. The function PEMreadbioex reads a PEM file from a BIO and parses and decodes the "name" for example, "CERTIFICATE", any header data, and the payload data. If the function succeeds, then the "nameout," "header," and "data"...

openssl: X.400 address type confusion in X.509 GeneralName

A type confusion vulnerability was found in OpenSSL when OpenSSL X.400 addresses processing inside an X.509 GeneralName. When CRL checking is enabled for example, the application sets the X509VFLAGCRLCHECK flag, this vulnerability may allow an attacker to pass arbitrary pointers to a memcmp call,...

openssl: timing attack in RSA Decryption implementation

A timing-based side channel exists in the OpenSSL RSA Decryption implementation, which could be sufficient to recover a ciphertext across a network in a Bleichenbacher style attack. To achieve a successful decryption, an attacker would have to be able to send a very large number of trial messages...
