Dostępne jest nowe wydanie linii stabilnej OpenWrt 19.07.5. Poprawiono kilka rzeczy związanych z bezpieczeństwem ( bibliotekę systemową musl), dlatego też zaleca się aktualizację systemu do najnowszej dostępnej wersji.

Informacje o wydaniu (EN):
The OpenWrt community is proud to announce the fifth service release of OpenWrt 19.07. It focuses on fixing several regression as well as security issues.

Main changes from OpenWrt 19.07.4

Security fixes
* Security Advisory 2020-12-09-2 - libuci import heap use after free (CVE-2020-28951)
* Security Advisory 2020-12-09-1 - Linux kernel - ICMP rate limiting can be used to facilitate DNS poisoning attack (CVE-2020-25705)
* musl: fix possible destination buffer overflow in some applications (CVE-2020-28928)

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 19.07.5 or later versions whenever possible.

Major bug fixes
* Fix regression in 19.07.4 causing transmit timeout and packet loss on mt7620 devices: FS#3332

* Fix long-standing instability issue on Ethernet link on several ath79 devices: FS#2216, FS#2730, FS#3225

Device support
* Various fixes for My Net Range Extender, PowerCloud Systems CAP324, D-Link DIR-645, Quad-E4G
* Support newer version of Turris Omnia
* Fix ath9k firmware extraction for UniFi AP
* Fix MAC address assignment on UniFi AC family (UniFi AC Mesh, UniFi AC LR, UniFi Lite)
* Allow booting espressobin with a mainline firmware

Various fixes and improvements
* Fix support for 3G USB modems
* uhttpd: fix spurious keepalive connection timeouts
* firewall: fix parsing of boolean attributes
* mac80211: do not allow bigger VHT MPDUs than the hardware supports

LuCI web interface
* Set the fallback default of rollback timeout to 90s
* luci-app-firewall: fix removing networks from zone (GH#4523, GH#4573)
* rpcd-mod-luci: handle lease files from all dnsmasq/odhcpd sections (GH#911, GH#4303, GH#4308)
* luci-app-firewall: rules: add ICMPv6 Packet Too Big (Type 2)
* Update translations from weblate

Core components
* Update Linux kernel from 4.14.195 to 4.14.209
* Update intel-microcode from 20190918 to 20200616
* Update amd-microcode from 20180524 to 20191218
