Description OSIDB Bzimport 2025-05-30 02:01:11 UTC 
Improper Validation of Unsafe Equivalence in punycode by the idna crate from Servo rust-url allows an attacker to create a punycode hostname that one part of a system might treat as distinct while another part of that system would treat as equivalent to another hostname.
