A new vulnerability has been disclosed in iOS Camera App that could be exploited to redirect users to a malicious website without their knowledge.
The vulnerability affects Apple’s latest iOS 11 mobile operating system for iPhone, iPad, and iPod touch devices and resides in the built-in QR code reader.
With iOS 11, Apple introduced a new feature that gives users ability to automatically read QR codes using their iPhone’s native camera app without requiring any third-party QR code reader app.
You need to open the Camera app on your iPhone or iPad and point the device at a QR code. If the code contains any URL, it will give you a notification with the link address, asking you to tap to visit it in Safari browser.
However, be careful — you may not be visiting the URL displayed to you, security researcher Roman Mueller discovered.
According to Mueller, the URL parser of built-in QR code reader for iOS camera app fails to detect the hostname in the URL, which allows attackers to manipulate the displayed URL in the notification, tricking users to visit malicious websites instead.
A severe programming bug has been found in APFS file system for macOS High Sierra operating system that exposes passwords of encrypted external drives in plain text.
Introduced two years ago, APFS (Apple File System) is an optimized file system for flash and SSD-based storage solutions running MacOS, iOS, tvOS or WatchOS, and promises strong encryption and better performance.
Discovered by forensic analyst Sarah Edwards, the bug leaves encryption password for a newly created APFS volume (e.g., encrypting USB drive using Disk Utility) in the unified logs in plaintext, as well as while encrypting previously created but unencrypted volumes.
“Why is this a big deal? Well, passwords stored in plaintext can be discovered by anyone with unauthorized access to your machine, and malware can collect log files as well and send them off to someone with malicious intent,” Edwards said.
One of the most important feature of Nagios is the notification system; by default Nagios will use the local mail daemon (mail) to send all the notifications.
Maybe this kind of system was working fine in past, but today, with this huge amount of spam circulating all over the world, this kind of emails from a not verified source can be filtered by the same company antispam system.
In order to avoid this issue I will explain how to configure Nagios using an external smtp server also with smtp authentication.
