Description

This security bulletin contains information about 2 secuirty vulnerabilities.


1) Buffer overflow (CVE-ID: CVE-2021-38297)

The vulnerability allows a remote attacker to execute arbitrary code on the target system.

The vulnerability exists due to a boundary error. A remote attacker can trigger memory corruption via large arguments in a function invocation from a WASM module, when GOARCH=wasm GOOS=js is used.


2) Unchecked Return Value (CVE-ID: CVE-2022-23806)

The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.

The vulnerability exists due to unchecked return value within the Curve.IsOnCurve() function in crypto/elliptic. A remote attacker can force the application to incorrectly return true in situations with a big.Int value that is not a valid field element. As a result, an attacker can modify application flow, which can lead to unauthorized data modification or denial of service.
