ALPINE-CVE-2020-10932

An issue was discovered in Arm Mbed TLS before 2.16.6 and 2.7.x before 2.7.15. An attacker that can get precise enough side-channel measurements can recover the long-term ECDSA private key by 1 reconstructing the projective coordinate of the result of scalar multiplication by exploiting side...

CVE-2019-14317

wolfSSL and wolfCrypt 4.1.0 and earlier formerly known as CyaSSL generate biased DSA nonces. This allows a remote attacker to compute the long term private key from several hundred DSA signatures via a lattice attack. The issue occurs because dsa.c fixes two bits of the generated nonces...

CVE-2019-13628

wolfSSL and wolfCrypt 4.0.0 and earlier when configured without --enable-fpecc, --enable-sp, or --enable-sp-math contain a timing side channel in ECDSA signature generation. This allows a local attacker, able to precisely measure the duration of signature operations, to infer information about th...

Name of the Vulnerable Software and Affected Versions Arm Mbed TLS versions 2.16.6 and earlier Arm Mbed TLS versions 2.7.x through 2.7.14 Description An issue was discovered in Arm Mbed TLS where an attacker can recover the long-term ECDSA private key by exploiting side channels in the conversion...

Three Questions for Billy Brumley on the OpenSSL Timing Attack

Timing attacks have been a problem for designers of cryptosystems–as well as for people implementing those systems–for a long time. They’ve plagued just about every popular system, and although practical attacks have been demonstrated many times, the problem and what can be done to defend against...

OpenSSL leaks ECDSA private key through a remote timing attack

Overview The OpenSSL ladder implementation for scalar multiplication of points on elliptic curves over binary fields is susceptible to a timing attack vulnerability. This vulnerability can be used to steal the private key of a TLS server that authenticates with ECDSA signatures and binary curves...
