NVD Description

Note: Versions mentioned in the description apply only to the upstream rust-toolset:rhel8/rust-src package and not the rust-toolset:rhel8/rust-src package as distributed by RHEL. See How to fix? for RHEL:8 relevant fixed versions and status.

library/std/src/net/parser.rs in Rust before 1.53.0 does not properly consider extraneous zero characters at the beginning of an IP address string, which (in some situations) allows attackers to bypass access control that is based on IP addresses, because of unexpected octal interpretation.
