A denial-of-service issue was addressed with improved memory handling. This issue is fixed in iOS 16.5 and iPadOS 16.5, macOS Ventura 13.4. Opening a PDF file may lead to unexpected app termination

An integer overflow was addressed with improved input validation. This issue is fixed in watchOS 8.8.1, iOS 16.5.1 and iPadOS 16.5.1, iOS 15.7.7 and iPadOS 15.7.7, macOS Big Sur 11.7.8, macOS Monterey 12.6.7, macOS Ventura 13.4.1, watchOS 9.5.2. An app may be able to execute arbitrary code with kernel privileges. Apple is aware of a report that this issue may have been actively exploited against versions of iOS released before iOS 15.7.

Dell BIOS contains an Out-of-bounds Write vulnerability. An unauthenticated physical attacker may potentially exploit this vulnerability, leading to denial of service.

Dell BIOS contains an Improper Input Validation vulnerability. An unauthenticated physical attacker may potentially exploit this vulnerability to perform arbitrary code execution.

Dell BIOS contains an improper authentication vulnerability. A locally authenticated malicious user may potentially exploit this vulnerability by bypassing certain authentication mechanisms in order to elevate privileges on the system.

Dell BIOS contains an improper input validation vulnerability. A local authenticated malicious user with administrator privileges may potentially exploit this vulnerability in order to modify a UEFI variable.

Dell VxRail, version(s) 8.0.100 and earlier contain a denial-of-service vulnerability in the upgrade functionality. A remote unauthenticated attacker could potentially exploit this vulnerability, leading to degraded performance and system malfunction.

OpenPrinting CUPS is a standards-based, open source printing system for Linux and other Unix-like operating systems. Starting in version 2.0.0 and prior to version 2.4.6, CUPS logs data of free memory to the logging service AFTER the connection has been closed, when it should have logged the data right before. This is a use-after-free bug that impacts the entire cupsd process. The exact cause of this issue is the function `httpClose(con->http)` being called in `scheduler/client.c`. The problem is that httpClose always, provided its argument is not null, frees the pointer at the end of the call, only for cupsdLogClient to pass the pointer to httpGetHostname. This issue happens in function `cupsdAcceptClient` if LogLevel is warn or higher and in two scenarios: there is a double-lookup for the IP Address (HostNameLookups Double is set in `cupsd.conf`) which fails to resolve, or if CUPS is compiled with TCP wrappers and the connection is refused by rules from `/etc/hosts.allow` and `/etc/...

The "nOAuth" attack allows cross-platform spoofing and full account takeovers, and enterprises need to remediate the issue immediately, researchers warn.
