CVE-2020-17478 (2020-08-10)

ECDSA/EC/Point.pm in Crypt::Perl before 0.33 does not properly consider timing attacks against the EC point multiplication algorithm.

CVE-2020-13895 (2020-06-07)

Crypt::Perl::ECDSA in the Crypt::Perl (aka p5-Crypt-Perl) module before 0.32 for Perl fails to verify correct ECDSA signatures when r and s are small and when s = 1. This happens when using the curve secp256r1 (prime256v1). This could conceivably have a security-relevant impact if an attacker wishes to use public r and s values when guessing whether signature verification will fail.

NAME

Crypt::Perl::X509::Extension::ct_precert_scts - X.509 ct_precert_scts extension

SYNOPSIS

my $extn = Crypt::Perl::X509::Extension::ct_precert_scts->new(
    {
        log_id => ..,
        timestamp => ..,
        extensions => [ .. ],
        signature_algorithm => '..',
    },
    # ..
);

DESCRIPTION

Instances of this class represent a ct_precert_scts extension of an X.509 (SSL) certificate.

You probably don’t need to instantiate this class directly; see Crypt::Perl::PKCS10 and Crypt::Perl::X509 for the way this module is meant to be used.
