Summary

mdanter/ecc affected by timing vulnerability in cryptographic side-channels

Details

phpecc, as used in all versions of mdanter/ecc, as well as paragonie/ecc before 2.0.1, has a branch-based timing leak in Point addition. (This Composer package is also known as phpecc/phpecc on GitHub, previously known as the Matyas Danter ECC library.)

Paragon Initiative Enterprises hard-forked phpecc/phpecc and discovered the issue in the original code, then released v2.0.1 which fixes the vulnerability. The upstream code is no longer maintained and remains vulnerable for all versions.
