gnark-crypto allows unchecked memory allocation during vector deserialization

The issue has been reported by @raefko from @fuzzinglabs. Excerpts from the report: A critical vulnerability exists in the gnark-crypto library's Vector.ReadFrom function that allows an attacker to trigger arbitrary memory allocation by crafting malicious input data. An attacker can cause the...

GHSA-FR8M-434R-G3XP gnark-crypto doesn't range check input values during ECDSA and EdDSA signature deserialization

Impact During deserialization of ECDSA and EdDSA signatures gnark-crypto did not check that the values are in the range 1, n-1 with n being the corresponding modulus either base field modulus in case of R in EdDSA, and scalar field modulus in case of s,r in ECDSA and s in EdDSA. As this also...

Denial Of Service (DoS)

github.com/consensys/gnark is vulnerable to Denial of Service DoS. The vulnerability is due to the fake-GLV scalar multiplication algorithm not converging quickly enough for certain inputs, which allows an attacker to trigger excessive computation and cause service disruption...

SUSE CVE-2025-58157

gnark is a zero-knowledge proof system framework. In version 0.12.0, there is a potential denial of service vulnerability when computing scalar multiplication is using the fake-GLV algorithm. This is because the algorithm didn't converge quickly enough for some of the inputs. This issue has been...

Denial of Service (DoS)

Overview Affected versions of this package are vulnerable to Denial of Service DoS via the QuoRem function in the eisenstein.go file. Details Denial of Service DoS describes a family of attacks, all aimed at making a system inaccessible to its intended and legitimate users. Unlike other...

Signature Malleability

github.com/consensys/gnark is vulnerable to signature malleability. The vulnerability is due to improper validation of the S value in EdDSA and ECDSA signatures not enforcing 0 ≤ S order, which allows an attacker to create multiple valid signatures for the same public input, potentially enabling...
