Created php tracking bugs for this issue: Affects: fedora-all [bug 1339950] php-5.6.22-1.fc23 has been pushed to the Fedora 23 stable repository. If problems still persist, please make note of it in this bug report. php-5.6.22-1.fc24 has been pushed to the Fedora 24 stable repository. If problems still persist, please make note of it in this bug report. php-5.6.22-1.fc22 has been pushed to the Fedora 22 stable repository. If problems still persist, please make note of it in this bug report. This issue is a very limited information leak / out of bounds read, caused by a failure to nul terminate string in certain cases. The use of term "leak" is misleading, as it's not a resource leak / failure to de-allocate memory after its effective life time. Practically, only few bytes or memory are disclosed, unlikely to disclose sensitive information. This issue is in the intl (Internationalization) extension. In Red Hat products, this extension is packaged separately in php-intl sub-RPM. Systems without that package installed can not be affected by this issue. This issue has been addressed in the following products: Red Hat Software Collections for Red Hat Enterprise Linux 6 Red Hat Software Collections for Red Hat Enterprise Linux 6.7 EUS Red Hat Software Collections for Red Hat Enterprise Linux 7 Red Hat Software Collections for Red Hat Enterprise Linux 7.2 EUS Red Hat Software Collections for Red Hat Enterprise Linux 7.3 EUS Via RHSA-2016:2750 https://rhn.redhat.com/errata/RHSA-2016-2750.html |
