EUVD-2026-14377

Versions of the package jsrsasign before 11.1.1 are vulnerable to Missing Cryptographic Step via the KJUR.crypto.DSA.signWithMessageHash process in the DSA signing implementation. An attacker can recover the private key by forcing r or s to be zero, so the library emits an invalid signature witho...

DEBIAN-CVE-2022-24884

ecdsautils is a tiny collection of programs used for ECDSA keygen, sign, verify. ecdsaverifypreparelegacy does not check whether the signature values r and s are non-zero. A signature consisting only of zeroes is always considered valid, making it trivial to forge signatures. Requiring multiple...
