Security Bulletin

This security bulletin contains information about 4 vulnerabilities.

1) Incorrect authorization

EUVDB-ID: #VU62037

Risk: Low

CVSSv3.1:

CVE-ID: CVE-2022-23773

CWE-ID: CWE-863 - Incorrect Authorization

Exploit availability: Yes

Description

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.

Mitigation

Install updates from vendor's website.

2) Unchecked Return Value

EUVDB-ID: #VU62036

Risk: Medium

CVSSv3.1:

CVE-ID: CVE-2022-23806

CWE-ID: CWE-252 - Unchecked Return Value

Exploit availability: No

Description

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.

Mitigation

Install updates from vendor's website.

EUVDB-ID: #VU64269

Risk: Low

CVSSv3.1:

CVE-ID: CVE-2022-28327

CWE-ID: CWE-190 - Integer overflow

Exploit availability: No

Description

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.

Mitigation

Install updates from vendor's website.
