A cookie management issue was addressed with improved checks. This issue affected versions prior to iOS 11.4.1, macOS High Sierra 10.13.6, tvOS 11.4.1, watchOS 4.3.2, iTunes 12.8 for Windows, iCloud for Windows 7.6.

Accounts. A privacy issue in the handling of Open Directory records was addressed with improved indexing.

DesktopServices. A permissions issue existed in which execute permission was incorrectly granted. This issue was addressed with improved permission validation.

IOGraphics. An out-of-bounds read issue existed that led to the disclosure of kernel memory. This was addressed with improved input validation.

An information leakage flaw is found in the way Linux kernel saves and restores Floating Point Unit(FPU) state during task switch. There are two ways, one is to save & restore FPU state during task context switch. And second is to defer FPU state save & restore until an FP instruction is invoked by the current task. First is called as "Eager FPU Restore" and second is known as "Lazy FPU Restore" scheme.

Linux kernel which follows the "Lazy FPU Restore" scheme is vulnerable to the FPU state information leakage issue. An unprivileged local attacker could use this flaw to read FPU state bits by conducting targeted cache side-channel attacks, similar to Meltdown attack disclosed earlier this year.

A vulnerability in Bluetooth pairing potentially allows an attacker with physical proximity (within 30 meters) to gain unauthorized access via an adjacent network, intercept traffic and send forged pairing messages between two vulnerable Bluetooth devices. This may result in information disclosure, elevation of privilege and/or denial of service.

If a script accepts an external input and outputs it without modification as a part of HTTP responses, an attacker can use newline characters to deceive the clients that the HTTP response header is stopped at there, and can inject fake HTTP responses after the newline characters to show malicious contents to the clients.
