GSD-2019-10764

Vulnerability from gsd - Updated: 2023-12-13 01:23
Details
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.
