CVE-2020-14966 (GCVE-0-2020-14966)

Vulnerability from cvelistv5 – Published: 2020-06-22 11:20 – Updated: 2024-08-04 13:00

Summary

An issue was discovered in the jsrsasign package through 8.0.18 for Node.js. It allows a malleability in ECDSA signatures by not checking overflows in the length of a sequence and '0' characters appended or prepended to an integer. The modified signatures are verified as valid. This could have a security-relevant impact if an application relied on a single canonical signature.

Severity

No CVSS data available.
