Toshifumi Sakaguchi discovered that the patch applied to pdns-recursor, a recursive DNS server, fixing CVE-2015-1868, was insufficient in some cases, allowing remote attackers to cause a denial of service (service-affecting CPU spikes and in some cases a crash). For the stable distribution (jessie), this problem has been fixed in version 3.6.2-2+deb8u2. For the testing distribution (stretch), this problem has been fixed in version 3.7.3-1. For the unstable distribution (sid), this problem has been fixed in version 3.7.3-1. We recommend that you upgrade your pdns-recursor packages.
