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)
