v1.1.0->v1.6.1GitHub Vulnerability Alerts
CVE-2023-1732
Impact
When sampling randomness for a shared secret, the implementation of Kyber and FrodoKEM, did not check whether
crypto/rand.Read()returns an error. In rare deployment cases (error thrown by theRead()function), this could lead to a predictable shared secret.The tkn20 and blindrsa components did not check whether enough randomness was returned from the user provided randomness source. Typically the user provides
crypto/rand.Reader, which in the vast majority of cases will always return the right number random bytes. In the cases where it does not, or the user provides a source that does not, the blinding for blindrsa is weak and integrity of the plaintext is not ensured in tkn20.Patches
The fix was introduced in CIRCL v. 1.3.3
GHSA-9763-4f94-gfch
Impact
On some platforms, when an attacker can time decapsulation of Kyber on forged cipher texts, they could possibly learn (parts of) the secret key.
Does not apply to ephemeral usage, such as when used in the regular way in TLS.
Patches
Patched in 1.3.7.
References
CVE-2025-8556
Impact
The CIRCL implementation of FourQ fails to validate user-supplied low-order points during Diffie-Hellman key exchange, potentially allowing attackers to force the identity point and compromise session security.
Moreover, there is an incorrect point validation in ScalarMult can lead to incorrect results in the isEqual function and if a point is on the curve.
Patches
Version 1.6.1 (https://github.com/cloudflare/circl/tree/v1.6.1) mitigates the identified issues.
We acknowledge Alon Livne (Botanica Software Labs) for the reported findings.
