CVE-2021-38194

An issue was discovered in the ark-r1cs-std crate before 0.3.1 for Rust. It does not enforce any constraints in the FieldVar::mulbyinverse method. Thus, a prover can produce a proof that is unsound but is nonetheless verified...

Mozilla Rust has an unspecified vulnerability (CNVD-2021-61409)

Rust is a general-purpose, compiled programming language from the Mozilla Foundation. a security vulnerability in ark-r1cs-std crate in Mozilla Rust before 0.3.1, which stems from FieldVar:: the mulbyinverse method does not enforce any constraints and can be exploited by an attacker to launch...

CVE-2021-38194

The CVE-2021-38194 issue affects the ark-r1cs-std crate for Rust (versions before 0.3.1). FieldVar::mul_by_inverse does not enforce constraints, allowing a malicious prover to produce an unsound proof that still verifies. The problem is caused by missing constraint checks in this method, compromi...

Flaw in `FieldVar::mul_by_inverse` allows unsound R1CS constraint systems

Versions 0.2.0 to 0.3.0 of ark-r1cs-std did not enforce any constraints in the FieldVar::mulbyinverse method, allowing a malicious prover to produce an unsound proof that passes all verifier checks. This method was used primarily in scalar multiplication for shortweierstrass::ProjectiveVar. This...
