GHSA-P73V-QH88-FQC2

Vulnerability from github – Published: 2022-05-24 16:57 – Updated: 2022-05-24 16:57

Details

MatrixSSL 4.2.1 and earlier contains a timing side channel in ECDSA signature generation. This allows a local or a remote attacker, able to measure the duration of hundreds to thousands of signing operations, to compute the private key used. The issue occurs because crypto/pubkey/ecc_math.c scalar multiplication leaks the bit length of the scalar.
