"Description": "This update upgrades ldns to version 1.8.1-alt1. \nSecurity Fix(es):\n\n * BDU:2022-05877: Уязвимость функции ldns_rr_new_frm_str_internal библиотеки DNS LDNS, позволяющая нарушителю получить доступ к конфиденциальным данным\n\n * BDU:2022-05917: Уязвимость функции ldns_nsec3_salt_data библиотеки DNS LDNS, позволяющая нарушителю получить доступ к конфиденциальным данным\n\n * BDU:2022-05943: Уязвимость компонента parse.c библиотеки DNS LDNS, позволяющая нарушителю получить доступ к конфиденциальным данным, нарушить их целостность, а также вызвать отказ в обслуживании\n\n * CVE-2017-1000231: A double-free vulnerability in parse.c in ldns 1.7.0 have unspecified impact and attack vectors.\n\n * CVE-2017-1000232: A double-free vulnerability in str2host.c in ldns 1.7.0 have unspecified impact and attack vectors.\n\n * 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.\n\n * 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.",
