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.

Changes for version 0.1

  • PKCS #10 CSR generation (RSA or ECDSA)
  • Small optimizations to RSA generation and associated POD
  • ASN1 prepare() errors now include the template’s first 32 bytes
