========================================================================== Ubuntu Security Notice USN-3491-1 November 22, 2017
ldns vulnerabilities ==========================================================================
A security issue affects these releases of Ubuntu and its derivatives:
- Ubuntu 17.10 - Ubuntu 17.04 - Ubuntu 16.04 LTS - Ubuntu 14.04 LTS
Summary:
Several security issues were fixed in ldns.
Software Description: - ldns: ldns library for DNS programming
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)
Update instructions:
The problem can be corrected by updating your system to the following package versions:
Ubuntu 17.10: libldns2 1.7.0-1ubuntu1.17.10.1
