Summary

The Elliptic package version 6.5.6 for Node.js contains a vulnerability related to ECDSA signature malleability. This issue arises from the allowance of BER-encoded signatures, which can lead to the creation of valid yet different ECDSA signatures for the same message. This malleability poses risks to the integrity of cryptographic operations and can be exploited in various attacks, potentially undermining the security of applications relying on this package. Developers using the Elliptic package should be aware of this vulnerability and take appropriate measures to mitigate its impacts.
