Security Bulletin
This security bulletin contains information about 2 vulnerabilities.
1) 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
DescriptionThe 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.

2) 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
DescriptionThe 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.
