The OpenWrt community is proud to announce the sixth service release of OpenWrt 19.07. It focuses on fixing several security issues.

Main changes from OpenWrt 19.07.5

Security fixes
* Security Advisory 2021-01-19-1 - dnsmasq multiple vulnerabilities CVE-2020-25681, CVE-2020-25682, CVE-2020-25683, CVE-2020-25687, CVE-2020-25684, CVE-2020-25685 and CVE-2020-25686)
* openssl: NULL pointer deref in GENERAL_NAME_cmp function can lead to a DOS attack. (CVE-2020-1971)

Note: security fixes for most packages can also be applied by upgrading only the affected packages on running devices, without the need for a full firmware upgrade. This can be done with opkg update; opkg upgrade the_package_name or through the LuCI web interface.

Nevertheless, we encourage all users to upgrade their devices to OpenWrt 19.07.6 or later versions whenever possible.

* Fix iOS 14 tethering problem

Device support
* Enable LED VCC for Asus RT-AC51U
