Package : ecdsautils
Version : 0.3.2+git20151018-2+deb9u1
CVE ID : CVE-2022-24884

In ecdsautils, a collection of ECDSA elliptic curve cryptography command
line tools, an improper verification of cryptographic signatures was
detected. A signature consisting only of zeroes is always considered
valid, making it trivial to forge signatures.

For Debian 9 stretch, this problem has been fixed in version
0.3.2+git20151018-2+deb9u1.

We recommend that you upgrade your ecdsautils packages.
