FYI, there's a rhel-6.7 bug for this already: https://bugzilla.redhat.com/show_bug.cgi?id=1144019 This issue has been addressed in the following products: Red Hat Enterprise Linux 6 Via RHSA-2015:0863 https://rhn.redhat.com/errata/RHSA-2015-0863.html Statement: This issue did not affect the versions of glibc as shipped with Red Hat Enterprise Linux 5 as they did not include the vulnerable code, which was introduced in later versions. Is there a plan to address the issue in RHEL-7? Any updates on whether this will be fixed in RHEL7? It's particularly easy to trigger on a docker host (we have 4 concurrent short-lived containers spinning up every few minutes). As soon as we have high load, DNS queries break until we restart the daemon. This issue has been addressed in the following products: Red Hat Enterprise Linux 7 Via RHSA-2015:2199 https://rhn.redhat.com/errata/RHSA-2015-2199.html This issue has been addressed in the following products: Red Hat Enterprise Linux 7.1 EUS - Server and Compute Node Only Red Hat Enterprise Linux 7.1 EUS - Server and Compute Node Only Via RHSA-2015:2589 https://rhn.redhat.com/errata/RHSA-2015-2589.html This issue has been addressed in the following products: Red Hat Enterprise Linux 6.5 Advanced Update Support Via RHSA-2016:1207 https://access.redhat.com/errata/RHSA-2016:1207 |
