UpstreamEPSS 2.7% - CVE-2017-1000232
A double-free vulnerability in str2host.c in ldns 1.7.0 have unspecified impact and attack vectors.
UpstreamEPSS 2.3% - CVE-2020-19860
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.
UpstreamEPSS 1.3% - CVE-2020-19861
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.
