CVE-2018-0495

Libgcrypt before 1.7.10 and 1.8.x before 1.8.3 allows a memory-cache side-channel attack on ECDSA signatures that can be mitigated through the use of blinding during the signing process in the gcryeccecdsasign function in cipher/ecc-ecdsa.c, aka the Return Of the Hidden Number Problem or ROHNP. T...

CVE-2018-0495

CVE-2018-0495 affects Libgcrypt prior to 1.7.10 and 1.8.x prior to 1.8.3. The root cause is a memory-cache side-channel (ROHNP) in the ECDSA signing path (_gcry_ecc_ecdsa_sign in cipher/ecc-ecdsa.c), enabling an attacker with local or co-resident VM access to recover ECDSA private keys. Mitigatio...

openssl: Bignum squaring may produce incorrect results

It was found that OpenSSL's BigNumber Squaring implementation could produce incorrect results under certain special conditions. This flaw could possibly affect certain OpenSSL library functionality, such as RSA blinding. Note that this issue occurred rarely and with a low probability, and there i...

syncthing: information leakage

This issue can affect RSA computations in crypto/rsa, which is used by crypto/tls. TLS servers on 32-bit systems could plausibly leak their RSA private key due to this issue. Other protocol implementations that create many RSA signatures could also be impacted in the same way. Specifically,...

crypto++: private key recovery

Evgeny Sidorov discovered that it is possible to recover the private key when using Rabin-Williams signatures due to a bad interaction with the blinding value used to mask private key operations. The bad interaction had to do with the random value not meeting certain Jacobi requirements, which...
