elliptic-php up to 1.0.5 Private Key Elliptic-Curve race condition

CVSS Meta Temp Score CVSS is a standardized scoring system to determine possibilities of attacks. The Temp Score considers temporal factors like disclosure, exploit and countermeasures. The unique Meta Score calculates the average score of different sources to provide a normalized scoring system.	Current Exploit Price (≈) Our analysts are monitoring exploit markets and are in contact with vulnerability brokers. The range indicates the observed or calculated exploit price to be seen on exploit markets. A good indicator to understand the monetary effort required for and the popularity of an attack.	CTI Interest Score Our Cyber Threat Intelligence team is monitoring different web sites, mailing lists, exploit markets and social media networks. The CTI Interest Score identifies the interest of attackers and the security community for this specific vulnerability in real-time. A high score indicates an elevated risk to be targeted for this vulnerability.

Detailsinfo

A vulnerability was found in elliptic-php up to 1.0.5 (Programming Language Software). It has been declared as problematic. Affected by this vulnerability is an unknown function of the component Private Key. The manipulation with an unknown input leads to a race condition vulnerability (Elliptic-Curve). The CWE definition for the vulnerability is CWE-362. The product contains a code sequence that can run concurrently with other code, and the code sequence requires temporary, exclusive access to a shared resource, but a timing window exists in which the shared resource can be modified by another code sequence that is operating concurrently. As an impact it is known to affect confidentiality. The summary by CVE is:

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.

The weakness was published 11/18/2019. This vulnerability is known as CVE-2019-10764 since 04/03/2019. The exploitation appears to be difficult. The attack can be launched remotely. The exploitation doesn't need any form of authentication. The technical details are unknown and an exploit is not publicly available.

There is no information about possible countermeasures known. It may be suggested to replace the affected object with an alternative product.
