Timing Attacks and Scalar Leakage Vulnerability in elliptic-php Versions Prior to 1.0.6

CVE-2019-10764 · HIGH Severity

CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:H/A:N

In elliptic-php versions priot to 1.0.6, Timing attacks might be possible which can result in practical recovery of the long-term private key generated by the library under certain conditions. Leakage of a bit-length of the scalar during scalar multiplication is possible on an elliptic curve which might allow practical recovery of the long-term private key.
