The DSA algorithm implementation in SAP SAPCRYPTOLIB 5.555.38 does not properly check signatures, which allows remote authenticated users to impersonate arbitrary users via unspecified vectors, aka SAP Security Note 2223008.

Crypto++ (aka cryptopp) through 5.6.4 does not document the requirement for a compile-time NDEBUG definition disabling the many assert calls that are unintended in production use, which might allow context-dependent attackers to obtain sensitive information by leveraging access to process memory after an assertion failure, as demonstrated by reading a core dump.

The _Rsa15 class in the RSA 1.5 algorithm implementation in jwa.py in jwcrypto before 0.3.2 lacks the Random Filling protection mechanism, which makes it easier for remote attackers to obtain cleartext data via a Million Message Attack (MMA).

EMC RSA BSAFE Micro Edition Suite (MES) 4.0.x and 4.1.x before 4.1.5, RSA BSAFE Crypto-C Micro Edition (CCME) 4.0.x and 4.1.x before 4.1.3, RSA BSAFE Crypto-J before 6.2.1, RSA BSAFE SSL-J before 6.2.1, and RSA BSAFE SSL-C before 2.8.9 allow remote attackers to discover a private-key prime by conducting a Lenstra side-channel attack that leverages an application's failure to detect an RSA signature failure during a TLS session.

The Bouncy Castle Java library before 1.51 does not validate a point is withing the elliptic curve, which makes it easier for remote attackers to obtain private keys via a series of crafted elliptic curve Diffie Hellman (ECDH) key exchanges, aka an "invalid curve attack."

Integer underflow in the base64-decoding implementation in EMC RSA BSAFE Micro Edition Suite (MES) 4.0.x before 4.0.8 and 4.1.x before 4.1.3, RSA BSAFE Crypto-C Micro Edition (Crypto-C ME) before 4.0.4 and 4.1, and RSA BSAFE SSL-C 2.8.9 and earlier allows remote attackers to cause a denial of service (memory corruption or segmentation fault) or possibly have unspecified other impact via crafted base64 data, a similar issue to CVE-2015-0292.

The InvertibleRWFunction::CalculateInverse function in rw.cpp in libcrypt++ 5.6.2 does not properly blind private key operations for the Rabin-Williams digital signature algorithm, which allows remote attackers to obtain private keys via a timing attack.

SAPCRYPTOLIB before 5.555.38, SAPSECULIB, and CommonCryptoLib before 8.4.30, as used in SAP NetWeaver AS for ABAP and SAP HANA, allows remote attackers to spoof Digital Signature Algorithm (DSA) signatures via unspecified vectors.

The Crypto.Random.atfork function in PyCrypto before 2.6.1 does not properly reseed the pseudo-random number generator (PRNG) before allowing a child process to access it, which makes it easier for context-dependent attackers to obtain sensitive information by leveraging a race condition in which a child process is created and accesses the PRNG within the same rate-limit period as another process.

The TLS implementation in the Bouncy Castle Java library before 1.48 and C# library before 1.8 does not properly consider timing side-channel attacks on a noncompliant MAC check operation during the processing of malformed CBC padding, which allows remote attackers to conduct distinguishing attacks and plaintext-recovery attacks via statistical analysis of timing data for crafted packets, a related issue to CVE-2013-0169.
