CVE-2024-42460

Name of the Vulnerable Software and Affected Versions Elliptic package version 6.5.6

Description The issue concerns ECDSA signature malleability due to a missing check for whether the leading bit of r and s is zero. This results in a cryptographic weakness. There is no information provided about the estimated number of potentially affected devices worldwide or real-world incidents where this issue was exploited.

Recommendations For Elliptic package version 6.5.6, apply the available patch immediately to mitigate risks. As a temporary workaround, consider adding a check for the leading bit of r and s to prevent ECDSA signature malleability until a patch is applied.
