Canonicalization Failures As a Recurring Vulnerability Class: Representation Divergence in Cryptographic Systems and Its Avoidance

Cryptographic systems operate on bytes but mean semantic objects. The translation between the two is rarely unique. Where this uniqueness is not enforced, an attack surface opens up as soon as a hash, a signature, replay protection, or consensus identity depends on the representation. The same...

Dependency on Vulnerable Third-Party Component

Overview matrix-nio is an A Python Matrix client library, designed according to sans I/O principles. Affected versions of this package are vulnerable to Dependency on Vulnerable Third-Party Component due to the use of a deprecated cryptographic dependency, which introduces multiple cryptographic...

Unity Linux 20.1050e / 20.1070e Security Update: ed25519-java (UTSA-2026-016772)

The Unity Linux 20 host has a package installed that is affected by a vulnerability as referenced in the UTSA-2026-016772 advisory. The implementation of EdDSA in EdDSA-Java aka ed25519-java through 0.3.0 exhibits signature malleability and does not satisfy the SUF-CMA Strong Existential...

Improper Certificate Validation

Nebula is vulnerable to Improper Certificate Validation. The vulnerability is due to ECDSA signature malleability in P256 certificates, which allows an attacker to generate a certificate with a different fingerprint and bypass certificate fingerprint-based blocklist entries...

GHSA-X3FF-W252-2G7J StableLib Ed25519 Signature Malleability via Missing S < L Check

Ed25519 Signature Malleability via Missing S = L to prevent signature malleability. When S = L, SB = S mod LB = S - LB, meaning two different 32-byte S values produce the same verification result. An attacker who observes a valid signature R, S can produce a second valid signature R, S + L for th...
