In its original specification, leading zero in Ipv4 string is interpreted as octal literals. So a IP address 0127.0.0.1 actually means 87.0.0.1. This confusion can lead to many security vulnerabilities. Therefore, in [IETF RFC 6943], it suggests to disallow octal/hexadecimal format in Ipv4 string all together. Existing implementation already disallows hexadecimal numbers. This commit makes Parser reject octal numbers. Fixes #83648. [IETF RFC 6943]: https://tools.ietf.org/html/rfc6943#section-3.1.1 |
