CVSS: 5.3EPSS: 0%CPEs: 5EXPL: 1CVE-2017-7764 – Mozilla: Domain spoofing with combination of Canadian Syllabics and other unicode blocks (MFSA 2017-16)
https://notcve.org/view.php?id=CVE-2017-7764
Characters from the "Canadian Syllabics" unicode block can be mixed with characters from other unicode blocks in the addressbar instead of being rendered as their raw "punycode" form, allowing for domain name spoofing attacks through character confusion. The current Unicode standard allows characters from "Aspirational Use Scripts" such as Canadian Syllabics to be mixed with Latin characters in the "moderately restrictive" IDN profile. We have changed Firefox behavior to match the upcoming Unicode version 10.0 which removes this category and treats them as "Limited Use Scripts.". This vulnerability affects Firefox < 54, Firefox ESR < 52.2, and Thunderbird < 52.2. Los caracteres del bloque unicode "Canadian Syllabics" pueden mezclarse con caracteres de otros bloques unicode en la barra de direcciones en lugar de ser presentados en su forma "punycode" sin procesar. • http://www.securityfocus.com/bid/99057 http://www.securitytracker.com/id/1038689 http://www.unicode.org/reports/tr31/tr31-26.html#Aspirational_Use_Scripts https://access.redhat.com/errata/RHSA-2017:1440 https://access.redhat.com/errata/RHSA-2017:1561 https://bugzilla.mozilla.org/show_bug.cgi?id=1364283 https://www.debian.org/security/2017/dsa-3881 https://www.debian.org/security/2017/dsa-3918 https://www.mozilla.org/security/advisories/mfsa2017-15 https://www.mozilla.org • CWE-20: Improper Input Validation •
