CVE-2019-18224 | 1 Gnu | 1 Libidn2 | 2024-11-21 | 7.5 HIGH | 9.8 CRITICAL |
idn2_to_ascii_4i in lib/lookup.c in GNU libidn2 before 2.1.1 has a heap-based buffer overflow via a long domain string. | |||||
CVE-2019-12290 | 1 Gnu | 1 Libidn2 | 2024-11-21 | 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. | |||||
CVE-2017-14062 | 2 Debian, Gnu | 2 Debian Linux, Libidn2 | 2024-11-21 | 7.5 HIGH | 9.8 CRITICAL |
Integer overflow in the decode_digit function in puny_decode.c in Libidn2 before 2.0.4 allows remote attackers to cause a denial of service or possibly have unspecified other impact. | |||||
CVE-2017-14061 | 1 Gnu | 1 Libidn2 | 2024-11-21 | 7.5 HIGH | 9.8 CRITICAL |
Integer overflow in the _isBidi function in bidi.c in Libidn2 before 2.0.4 allows remote attackers to cause a denial of service or possibly have unspecified other impact. |
