Astra Linux – Vulnerability in RustC
The library/std/src/net/parser.rs file in Rust before version 1.53.0 does not properly handle zero characters at the beginning of an IP address string. In some cases, this allows attackers to bypass access controls based on IP addresses due to incorrect octal interpretation of these characters...

CVE-2026-45191
Net::CIDR::Lite (Perl) is affected in versions before 0.24. The flaw is in CIDR mask handling: extraneous zero characters in masks are not properly validated, causing /00 and /01 (and other zero-padded forms) to pass validation and be parsed to the same prefix as the unpadded value, potentially a...
