Vulnerability from github – Published: 2018-09-10 15:19 – Updated: 2021-09-16 19:58

Summary

Sensitive Data Exposure in msrcrypto

Details

Versions of msrcrypto prior to 1.4.1 are vulnerable to Sensitive Data Exposure. The package's Elliptic Curve Cryptography (ECC) implementation may leak information about a server's private ECC key. It can also allow attackers to craft invalid ECDSA signatures that pass as valid. There is no published proof-of-concept for this vulnerability.

Recommendation

Upgrade to version 1.4.1 or later.

Severity ?

9.8 (Critical)
