NOTE: the vendor disputes this, stating 'There is no security issue here, because GMP safely aborts in case of an OOM condition. The only attack vector here is denial of service. However, if you allow attacker-controlled, unbounded allocations you have a DoS vector regardless of GMP's OOM behavior.'(CVE-2014-3591)

GNOME NetworkManager version 1.10.2 and earlier contains a Information Exposure (CWE-200) vulnerability in DNS resolver that can result in Private DNS queries leaked to local network's DNS servers, while on VPN. This vulnerability appears to have been fixed in Some Ubuntu 16.04 packages were fixed, but later updates removed the fix. cf. [link moved to references] an upstream fix does not appear to be available at this time.(CVE-2015-0837)");
