An anonymous reader quotes a report from ZDNet: As reported previously by ZDNet, the bug, dubbed "KRACK" -- which stands for Key Reinstallation Attack -- is at heart a fundamental flaw in the way Wi-Fi Protected Access II (WPA2) operates. According to security researcher and academic Mathy Vanhoef, who discovered the flaw, threat actors can leverage the vulnerability to decrypt traffic, hijack connections, perform man-in-the-middle attacks, and eavesdrop on communication sent from a WPA2-enabled device. In total, ten CVE numbers have been preserved to describe the vulnerability and its impact, and according to the U.S. Department of Homeland Security (DHS), the main affected vendors are Aruba, Cisco, Espressif Systems, Fortinet, the FreeBSD Project, HostAP, Intel, Juniper Networks, Microchip Technology, Red Hat, Samsung, various units of Toshiba and Ubiquiti Networks. A list of the patches available is below. For the most up-to-date list with links to each patch/statement (if available), visit ZDNet's article.Apple: The iPhone and iPad maker confirmed to sister-site CNET that fixes for iOS, macOS, watchOS and tvOS are in beta, and will be rolling it out in a software update in a few weeks.
Arris: a spokesperson said the company is "committed to the security of our devices and safeguarding the millions of subscribers who use them," and is "evaluating" its portfolio. The company did not say when it will release any patches.
Aruba: Aruba has been quick off the mark with a security advisory and patches available for download for ArubaOS, Aruba Instant, Clarity Engine and other software impacted by the bug.
AVM: This company may not be taking the issue seriously enough, as due to its "limited attack vector," despite being aware of the issue, will not be issuing security fixes "unless necessary."
Cisco: The company is currently investigating exactly which products are impacted by KRACK, but says that "multiple Cisco wireless products are affected by these vulnerabilities."
"Cisco is aware of the industry-wide vulnerabilities affecting Wi-Fi Protected Access protocol standards," a Cisco spokesperson told ZDNet. "When issues such as this arise, we put the security of our customers first and ensure they have the information they need to best protect their networks. Cisco PSIRT has issued a security advisory to provide relevant detail about the issue, noting which Cisco products may be affected and subsequently may require customer attention.
"Fixes are already available for select Cisco products, and we will continue publishing additional software fixes for affected products as they become available," the spokesperson said.
In other words, some patches are available, but others are pending the investigation.
Espressif Systems: The Chinese vendor has begun patching its chipsets, namely ESP-IDF and ESP8266 versions, with Arduino ESP32 next on the cards for a fix.
Fortinet: At the time of writing there was no official advisory, but based on Fortinet's support forum, it appears that FortiAP 5.6.1 is no longer vulnerable to most of the CVEs linked to the attack, but the latest branch, 5.4.3, may still be impacted. Firmware updates are expected.
FreeBSD Project: There is no official response at the time of writing.
Google: Google told sister-site CNET that the company is "aware of the issue, and we will be patching any affected devices in the coming weeks."
HostAP: The Linux driver provider has issued several patches in response to the disclosure.
Intel: Intel has released a security advisory listing updated Wi-Fi drives and patches for affected chipsets, as well as Intel Active Management Technology, which is used by system manufacturers.
Linux: As noted on Charged, a patch is a patch is already available and Debian builds can patch now, while OpenBSD was fixed back in July.
Netgear: Netgear has released fixes for some router hardware. The full list can be found here.
Microsoft: While Windows machines are generally considered safe, the Redmond giant isn't taking any chances and has released a security fix available through automatic updates.
MikroTik: The vendor has already released patches that fix the vulnerabilities.
OpenBSD: Patches are now available.
Ubiquiti Networks: A new firmware release, version 220.127.116.1137, protects users against the attack.
Wi-Fi Alliance: The group is offering a tool to detect KRACK for members and requires testing for the bug for new members.
Wi-Fi Standard: A fix is available for vendors but not directly for end users.
