openSUSE 15 Security Update : ldns (openSUSE-SU-2022:0675-1)

Description

The remote SUSE Linux SUSE15 host has packages installed that are affected by multiple vulnerabilities as referenced in the openSUSE-SU-2022:0675-1 advisory. - 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-2020-19860) - 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-2020-19861) Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.
