Design/Logic Flaw

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 whic...

elliptic-php competitive conditions issue vulnerability

elliptic-php is a PHP-based elliptic curve cryptographic library. A competitive condition issue vulnerability exists in versions of elliptic-php prior to 1.0.6, which can be exploited by an attacker to recover long-lived private keys...
