| CVE-2019-12290 | 1 Gnu | 1 Libidn2 | 2019-10-29 | 5.0 MEDIUM | 7.5 HIGH |
| GNU libidn2 before 2.2.0 fails to perform the roundtrip checks specified in RFC3490 Section 4.2 when converting A-labels to U-labels. This makes it possible in some circumstances for one domain to impersonate another. By creating a malicious domain that matches a target domain except for the inclusion of certain punycoded Unicode characters (that would be discarded when converted first to a Unicode label and then back to an ASCII label), arbitrary domains can be impersonated. | |||||
