Vulnerability from github – Published: 2019-11-20 01:34 – Updated: 2021-08-18 22:40

Summary

Timing attacks might allow practical recovery of the long-term private key

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.

Severity

7.4 (High)
