Description
This security bulletin contains information about 1 security vulnerability.
1) Input validation error (CVE-ID: CVE-2021-29923)
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.
Remediation
Install update from vendor's website.
