| CVE-2016-6263 | Hig | 0.49 | 7.5 | 0.04 | Sep 7, 2016 | The stringprep_utf8_nfkc_normalize function in lib/nfkc.c in libidn before 1.33 allows context-dependent attackers to cause a denial of service (out-of-bounds read and crash) via crafted UTF-8 data. | ||
| CVE-2016-6262 | Hig | 0.49 | 7.5 | 0.07 | Sep 7, 2016 | idn in libidn before 1.33 might allow remote attackers to obtain sensitive memory information by reading a zero byte as input, which triggers an out-of-bounds read, a different vulnerability than CVE-2015-8948. | ||
| CVE-2016-6261 | Hig | 0.49 | 7.5 | 0.04 | Sep 7, 2016 | The idna_to_ascii_4i function in lib/idna.c in libidn before 1.33 allows context-dependent attackers to cause a denial of service (out-of-bounds read and crash) via 64 bytes of input. | ||
| CVE-2015-8948 | Hig | 0.42 | 7.5 | 0.07 | Sep 7, 2016 | idn in GNU libidn before 1.33 might allow remote attackers to obtain sensitive memory information by reading a zero byte as input, which triggers an out-of-bounds read. | ||
| CVE-2026-57053 | 0.00 | — | 0.00 | Jun 23, 2026 | GNU libidn before 1.44 is prone to out-of-bounds reads of uninitialized memory in the ToUnicode APIs because of mishandling in idna_to_unicode_internal. The affected code is not present in libidn2. | |||
| CVE-2015-2059 | 0.00 | — | 0.03 | Aug 12, 2015 | The stringprep_utf8_to_ucs4 function in libin before 1.31, as used in jabberd2, allows context-dependent attackers to read system memory and possibly have other unspecified impact via invalid UTF-8 characters in a string, which triggers an out-of-bounds read. |
