crypto/x509: golang: Panic when validating certificates with DSA public keys in crypto/x509

A denial of service vector has been discovered in the golang crypto/x509 module. An attacker could craft an intermediate X.509 certificate containing a DSA public key and can crash a remote host with an unauthenticated call to any endpoint that verifies the certificate chain...

wolfSSL's ECCSI signature verifier wcVerifyEccsiHash decodes the r and s scalars from the signature blob via mpreadunsignedbin with no check that they lie in 1, q-1. A crafted forged signature could verify against any message for any identity, using only publicly-known constants...

Improper Verification of Cryptographic Signature

Overview Affected versions of this package are vulnerable to Improper Verification of Cryptographic Signature due to improper validation of the wcVerifyEccsiHash process. An attacker can bypass signature verification and impersonate any identity by submitting crafted signatures containing invalid...
