Security Bulletin
This security bulletin contains information about 4 vulnerabilities.
1) Incorrect authorization
EUVDB-ID: #VU62037
Risk: Low
CVSSv3.1: 3.9 [CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:L/A:N/E:P/RL:O/RC:C]
CVE-ID: CVE-2022-23773
CWE-ID:
CWE-863 - Incorrect Authorization
Exploit availability: Yes
DescriptionThe 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.

Q & A
Can this vulnerability be exploited remotely?
Yes. This vulnerability can be exploited by a remote authenticated user via the Internet.
Is there known malware, which exploits this vulnerability?
No. We are not aware of malware exploiting this vulnerability. However, proof of concept for this vulnerability is available.
2) Unchecked Return Value
EUVDB-ID: #VU62036
Risk: Medium
CVSSv3.1: 5.7 [CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:L/A:L/E:U/RL:O/RC:C]
CVE-ID: CVE-2022-23806
CWE-ID:
CWE-252 - Unchecked Return Value
Exploit availability: No
DescriptionThe 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
EUVDB-ID: #VU64269
Risk: Low
CVSSv3.1: 3.8 [CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:N/I:N/A:L/E:U/RL:O/RC:C]
CVE-ID: CVE-2022-28327
CWE-ID:
CWE-190 - Integer overflow
Exploit availability: No
DescriptionThe 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.

CVE-ID: CVE-2022-30631
CWE-ID:
CWE-400 - Resource exhaustion
Exploit availability: No
DescriptionThe 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.
