Description

This security bulletin contains information about 4 secuirty vulnerabilities.


1) Incorrect authorization (CVE-ID: CVE-2022-23773)

The vulnerability allows a remote attacker to bypass implemented security restrictions.

The vulnerability exists within cmd/go, which can misinterpret branch names that falsely appear to be version tags. This can lead to  a situation where an attacker can bypass implemented security restrictions and perform restricted actions, e.g. create tags when access was granted to create branches only.


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.


3) Integer overflow (CVE-ID: CVE-2022-28327)

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

The vulnerability exists due to integer overflow in the Golang's library crypto/elliptic. A remote attacker can send a specially crafted scalar input longer than 32 bytes to cause P256().ScalarMult or P256().ScalarBaseMult to panic and perform a denial of service attack.


4) Resource exhaustion (CVE-ID: CVE-2022-30631)

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

The vulnerability exists due to application does not properly control consumption of internal resources in Reader.Read method when handling an archive that contains a large number of concatenated 0-length compressed files. A remote attacker can trigger resource exhaustion and perform a denial of service (DoS) attack.
