| + | ====== Security ====== | ||
| + | See [[: | ||
| + | |||
| + | This page lists the processes, tools and mechanisms OpenWrt uses to the security of OpenWrt. | ||
| + | This covers the OpenWrt distribution with the official package feeds hosted at https:// | ||
| + | |||
| + | ===== Vulnerability reporting ===== | ||
| + | Security bugs should be reported in confidentiality to [[contact@openwrt.org]], | ||
| + | |||
| + | ===== Security advisories ===== | ||

| + | |||
| + | This only lists security advisories for components maintained directly by the OpenWrt team. This does not list all fixed security problems in third party components used by OpenWrt which can also affect the security of OpenWrt. We do not list known security problems in the Linux kernel, openssl and other third party components even when they affect use cases relevant for OpenWrt. The OpenWrt team monitors the upstream projects and backports security fixes for components used in the OpenWrt core repository to still supported OpenWrt versions. For example | ||

| + | ===== Support status ===== | ||
| + | This lists the currently support or not supported OpenWrt versions. | ||
| + | |||
| + | ^ Version ^ Current status ^ Projected EoL ^ | ||
| + | | 23.05 | Fully supported | - | | ||
| + | | 22.03 | Security maintenance | EoL (April 2024) | | ||
| + | | 21.02 | End of life | EoL (May 2023) | | ||
| + | | 19.07 | End of life | EoL (April 2022) | | ||
| + | | 18.06 | End of life | EoL | | ||
| + | | 17.01 | End of life | EoL | | ||
| + | | 15.05 | End of life | EoL | | ||
| + | |||
| + | The projected EoL can be extended later, depending on the future situation, like the release date of the next release. | ||
| + | |||
| + | The Version references the most recent stable version from this release branch. | ||
| + | |||
| + | * Fully supported means that the OpenWrt team provides updates for the core packages fixing security and other problems we are aware of. | ||
| + | * Security maintenance means that the OpenWrt team fixes only security problems in this release but no bugs any more. | ||
| + | * End of life means that we will *not* provide any updates also for severe security problem. Please update to more recent versions. | ||
| + | |||
| + | A OpenWrt major version will get into fully supported status after it was initially released. | ||
| + | When the next OpenWrt major version is released the old version will move into security maintenance mode. | ||
| + | A OpenWrt major version will move into end of Life 1 year after the initial release or 6 months after the release of the next major versions. The later date will be used. We plan to do a final minor release at the end of the support cycle. | ||
| + | |||
| + | This only covers the core OpenWrt packages and not the external package feeds hosted on github. | ||
| + | Some feed package maintainer do not take care of all OpenWrt versions where the the core components are still supported. | ||
| + | For the best security support we suggest everyone to upgrade to the most recent stable version. | ||
| + | |||
| + | ===== Identifying problems ===== | ||
| + | The OpenWrt project uses multiple tools to identify potential security problems. | ||
| + | The information are normally available for everyone and we appreciate fixes for problems reported by these tools form everyone. | ||
| + | |||
| + | ==== uscan ==== | ||
| + | The [[https:// | ||
| + | In addition the tool which generates this page also checks for existing CVEs assigned to the packages based on the Common Platform Enumeration (CPE) which is listed in the PKG_CPE_ID variable of many packages. | ||
| + | That page is updated weekly for master and the active release branches. | ||
| + | |||
| + | ==== Coverity Scan ==== | ||
| + | OpenWrt uses the commercial [[https:// | ||
| + | This scans one OpenWrt build per week and reports the problems found in the components developed in the OpenWrt project like procd and ubus, but not on (patched) third party components. | ||
| + | |||
| + | ===== Reproducible builds ===== | ||
| + | The [[https:// | ||
| + | This proves that the produced releases really match the delivered source code and no backdoors were introduced in the build process. | ||
| + | |||
| + | ===== Deliver to users ===== | ||
| + | OpenWrt operates multiple [[: | ||
| + | |||
| + | When a change to a package is committed to the OpenWrt base repository of package feed, the build bots are automatically detecting this change and will rebuild this package. | ||
| + | The newly built package can then be installed with opkg or be integrated with the image builder by users of OpenWrt. | ||
| + | This allows us to ship updates in about 2 days to the end users. | ||
| + | |||
| + | The kernel is normally located in its own partition and upgrades are not so easily possible. | ||
| + | Therefore this mechanism currently does not work for the kernel itself and kernel modules and a new minor release is needed to ship fixes to end users. | ||
| + | |||
| + | ===== Hardening build options ===== | ||
| + | OpenWrt activates some build hardening options in the [[https:// | ||
| + | Note that individual packages and/or targets may ignore or otherwise not respect these settings. | ||
