Timing Attack

Overview Affected versions of this package are vulnerable to Timing Attack in the ML-KEM Poly.toMsg, Poly.compressPoly, and PolyVec.compressPolyVec routines. An attacker can recover a long-term private key by sending ciphertexts and measuring the time taken by repeated decapsulation operations th...

CVE-2025-29780

CVE-2025-29780 affects the Python implementation of Post-Quantum Secure Feldman's Verifiable Secret Sharing (VSS) in the feldman_vss library, version 0.8.0b2 and earlier. Connected sources describe timing side-channel vulnerabilities in matrix operations, specifically in _find_secure_pivot and po...

CVE-2025-29779 Post-Quantum Secure Feldman's Verifiable Secret Sharing has Inadequate Fault Injection Countermeasures in `secure_redundant_execution`

Post-Quantum Secure Feldman's Verifiable Secret Sharing provides a Python implementation of Feldman's Verifiable Secret Sharing VSS scheme. In versions 0.8.0b2 and prior, the secureredundantexecution function in feldmanvss.py attempts to mitigate fault injection attacks by executing a function...

GHSA-JP37-5QHW-MFFW Sharks has a Bias of Polynomial Coefficients in Secret Sharing

Affected versions of this crate allowed for a bias when generating random polynomials for Shamir Secret Sharing, where instead of being within the range 0, 255 they were instead in the range 1, 255. A description from Cure53, who originally found the issue, is available: The correct method to...
