Summary
ldns vulnerabilities
Details

Leon Weber discovered that the ldns-keygen tool incorrectly set permissions on private keys. A local attacker could possibly use this issue to obtain generated private keys. This issue only applied to Ubuntu 14.04 LTS. (CVE-2014-3209)

Stephan Zeisberg discovered that ldns incorrectly handled memory when processing data. A remote attacker could use this issue to cause ldns to crash, resulting in a denial of service, or possibly execute arbitrary code. (CVE-2017-1000231, CVE-2017-1000232)
