There are 2 open security issues in bullseye.
2 issues left for the package maintainer to handle:
- CVE-2020-19860:
(needs triaging)
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-2020-19861:
(needs triaging)
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.
You can find information about how to handle these issues in the security team's documentation.
