Created httpd tracking bugs for this issue: Affects: fedora-all [bug 1560618] Upstream patch: https://svn.apache.org/viewvc?view=revision&revision=1824339 As per the upstream changelog, the following change was made for this flaw: Configure the regular expression engine to match '$' to the end of the input string only, excluding matching the end of any embedded newline characters. Behavior can be changed with new directive 'RegexDefaultOptions'. 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 7 Red Hat Software Collections for Red Hat Enterprise Linux 7.4 EUS Red Hat Software Collections for Red Hat Enterprise Linux 7.5 EUS Red Hat Software Collections for Red Hat Enterprise Linux 7.6 EUS Via RHSA-2018:3558 https://access.redhat.com/errata/RHSA-2018:3558 This issue has been addressed in the following products: Red Hat JBoss Core Services Via RHSA-2019:0366 https://access.redhat.com/errata/RHSA-2019:0366 This issue has been addressed in the following products: JBoss Core Services on RHEL 6 JBoss Core Services on RHEL 7 Via RHSA-2019:0367 https://access.redhat.com/errata/RHSA-2019:0367 Statement: The "FilesMatch" directive is not enabled in the default httpd configuration as shipped with Red Hat Enterprise Linux, and needs to be explicitly enabled. Therefore this flaw has no impact on the default versions of the httpd package as shipped with Red Hat Enterprise Linux. Red Hat Satellite 6 uses Red Hat Enterprise Linux 7's httpd package, and enables the "FilesMatch" directive. However, this is not believed to have an impact on security, as, in the context of a Satellite, no one is expected to have the ability to modify file names in the concerned directories. This is not considered as a vector for attack. This issue has been addressed in the following products: Red Hat Enterprise Linux 7 Via RHSA-2020:3958 https://access.redhat.com/errata/RHSA-2020:3958 |
