| CVE-2020-19861 | 0.00 | — | 0.01 | Jan 21, 2022 | When a zone file in ldns 1.7.1 is parsed, the function ldns_nsec3_salt_data is too trusted for the length value obtained from the zone file. When the memcpy is copied, the 0xfe - ldns_rdf_size(salt_rdf) byte data can be copied, causing heap overflow information leakage. | |||
| CVE-2020-19860 | 0.00 | — | 0.01 | Jan 21, 2022 | When ldns version 1.7.1 verifies a zone file, the ldns_rr_new_frm_str_internal function has a heap out of bounds read vulnerability. An attacker can leak information on the heap by constructing a zone file payload. | |||
| CVE-2014-3209 | 0.00 | — | 0.00 | Nov 16, 2014 | The ldns-keygen tool in ldns 1.6.x uses the current umask to set the privileges of the private key, which might allow local users to obtain the private key by reading the file. | |||
