Detailsinfo

A vulnerability was found in Elliptic Package 6.5.2 on node.js (JavaScript Library). It has been classified as critical. This affects an unknown functionality of the component ECDSA Signature Handler. The manipulation with an unknown input leads to a integer overflow vulnerability. CWE is classifying the issue as CWE-190. The product performs a calculation that can produce an integer overflow or wraparound, when the logic assumes that the resulting value will always be larger than the original value. This can introduce other weaknesses when the calculation is used for resource management or execution control. This is going to have an impact on confidentiality, integrity, and availability. The summary by CVE is:

The Elliptic package 6.5.2 for Node.js allows ECDSA signature malleability via variations in encoding, leading '\0' bytes, or integer overflows. This could conceivably have a security-relevant impact if an application relied on a single canonical signature.

The weakness was shared 06/04/2020. This vulnerability is uniquely identified as CVE-2020-13822 since 06/04/2020. It is possible to initiate the attack remotely. No form of authentication is needed for exploitation. Neither technical details nor an exploit are publicly available.

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