CVE-2019-12290 (GCVE-0-2019-12290)
Vulnerability from cvelistv5 – Published: 2019-10-22 15:14 – Updated: 2024-08-04 23:17
VLAI
Summary
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.

CVE-2019-12290 (GCVE-0-2019-12290)
Vulnerability from nvd – Published: 2019-10-22 15:14 – Updated: 2024-08-04 23:17
VLAI
Summary
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.
Severity
No CVSS data available.
