New Bluetooth Hack Affects Millions of Devices from Major Vendors

Yet another bluetooth hacking technique has been uncovered. A highly critical cryptographic vulnerability has been found affecting some Bluetooth implementations that could allow an unauthenticated, remote attacker in physical proximity of targeted devices to intercept, monitor or manipulate the...

Bluetooth implementations may not sufficiently validate elliptic curve parameters during Diffie-Hellman key exchange

Overview Bluetooth firmware or operating system software drivers may not sufficiently validate elliptic curve parameters used to generate public keys during a Diffie-Hellman key exchange, which may allow a remote attacker to obtain the encryption key used by the device. Description CWE-325: Missi...

openssl: Carry propagating bug in Montgomery multiplication

There is a carry propagating bug in the Broadwell-specific Montgomery multiplication procedure in OpenSSL 1.0.2 and 1.1.0 before 1.1.0c that handles input lengths divisible by, but longer than 256 bits. Analysis suggests that attacks against RSA, DSA and DH private keys are impossible. This is...

openssl: rsaz_1024_mul_avx2 overflow bug on x86_64

There is an overflow bug in the AVX2 Montgomery multiplication procedure used in exponentiation with 1024-bit moduli. No EC algorithms are affected. Analysis suggests that attacks against RSA and DSA as a result of this defect would be very difficult to perform and are not believed likely. Attack...
