CVE-2019-10764 (GCVE-0-2019-10764)

Vulnerability from cvelistv5 – Published: 2019-11-18 21:55 – Updated: 2024-08-04 22:32

Summary

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

No CVSS data available.
