It was discovered that ecdsautils, a collection of ECDSA elliptic curve cryptography CLI tools verified some cryptographic signatures incorrectly: A signature consisting only of zeroes was always considered valid, making it trivial to forge signatures. For the oldstable distribution (buster), this problem has been fixed in version 0.3.2+git20151018-2+deb10u1. For the stable distribution (bullseye), this problem has been fixed in version 0.3.2+git20151018-2+deb11u1. We recommend that you upgrade your ecdsautils packages.
