Security Bulletin

This security bulletin contains information about 7 vulnerabilities.

1) Resource exhaustion

EUVDB-ID: #VU54521

Risk: Medium

CVSSv3.1:

CVE-ID: CVE-2021-33196

CWE-ID: CWE-400 - Resource exhaustion

Exploit availability: No

Description

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 when parsing archives. A remote attacker can pass a specially crafted .zip file to the application, trigger resource exhaustion and perform a denial of service (DoS) attack.

Mitigation

Install update from vendor's website.

2) Improper Certificate Validation

EUVDB-ID: #VU55665

Risk: Medium

CVSSv3.1:

CVE-ID: CVE-2021-34558

CWE-ID: CWE-295 - Improper Certificate Validation

Exploit availability: Yes

Description

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

The vulnerability exists due to improper certificate verification in crypto/tls package in Go when processing X.509 certificates. The application does not properly assert that the type of public key in an X.509 certificate matches the expected type when doing a RSA based key exchange, allowing a malicious TLS server to cause a TLS client to panic.

Mitigation

Install update from vendor's website.

3) Input validation error

EUVDB-ID: #VU56829

Risk: Medium

CVSSv3.1:

CVE-ID: CVE-2021-29923

CWE-ID: CWE-20 - Improper Input Validation

Exploit availability: No

Description

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

The vulnerability exists due to insufficient validation of user-supplied input in net.ParseIP and net.ParseCIDR, as the Go interpreter does not properly consider extraneous zero characters at the beginning of an IP address octet. A remote attacker can bypass access control that is based on IP addresses, because of unexpected octal interpretation.

Mitigation

Install update from vendor's website.

4) Race condition

EUVDB-ID: #VU55668

Risk: Medium

CVSSv3.1:

CVE-ID: CVE-2021-36221

CWE-ID: CWE-362 - Concurrent Execution using Shared Resource with Improper Synchronization ('Race Condition')

Exploit availability: No

Description

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