https://notcve.org/view.php?id=CVE-2020-13895
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. La función Crypt::Perl::ECDSA en el módulo Crypt::Perl (también se conoce como p5-Crypt-Perl) versiones anteriores a 0.32 para Perl, no puede verificar las firmas correctas ECDSA cuando r y s son pequeñas y cuando s = 1. Esto se presenta cuando se usa la curva secp256r1 (prime256v1). • https://github.com/FGasper/p5-Crypt-Perl/commit/f960ce75502acf7404187231a706672f8369acb2 https://github.com/FGasper/p5-Crypt-Perl/issues/14 • CWE-347: Improper Verification of Cryptographic Signature •

Perl before 5.30.3 has an integer overflow related to mishandling of a "PL_regkind[OP(n)] == NOTHING" situation. A crafted regular expression could lead to malformed bytecode with a possibility of instruction injection. Perl versiones anteriores a 5.30.3, presenta un desbordamiento de enteros relacionado con un manejo inapropiado de una situación "PL_regkind[OP(n)] == NOTHING".
