Directory Traversal Allowing Local Apps to Access Sensitive User Data

A parsing issue in the handling of directory paths was addressed with improved path validation. This issue is fixed in macOS Sequoia 15.7.4, macOS Sonoma 14.8.4, macOS Tahoe 26.3, visionOS 26.3. An app may be able to access sensitive user data.

Idle locking function in MacOS 9 allows local users to bypass the password protection of idled sessions by selecting the "Log Out" option and selecting a "Cancel" option in the dialog box for an application that attempts to verify that the user wants to log out, which returns the attacker into the locked session.

A possible interaction between Apple MacOS X release 1.0 and Apache HTTP server allows remote attackers to cause a denial of service (crash) via a flood of HTTP GET requests to CGI programs, which generates a large number of processes.

MacOS uses weak encryption for passwords that are stored in the Users & Groups Data File.

Control Panel "Password Security" option for Apple Powerbooks allows attackers with physical access to the machine to bypass the security by booting it with an emergency startup disk and using a disk editor to modify the on/off toggle or password in the aaaaaaaAPWD file, which is normally inaccessible.

The (1) CertGetCertificateChain, (2) CertVerifyCertificateChainPolicy, and (3) WinVerifyTrust APIs within the CryptoAPI for Microsoft products including Microsoft Windows 98 through XP, Office for Mac, Internet Explorer for Mac, and Outlook Express for Mac, do not properly verify the Basic Constraints of intermediate CA-signed X.509 certificates, which allows remote attackers to spoof the certificates of trusted sites via a man-in-the-middle attack for SSL sessions, as originally reported for Internet Explorer and IIS.

A system does not present an appropriate legal message or warning to a user who is accessing it.

Idle locking function in MacOS 9 allows local attackers to bypass the password protection of idled sessions via the programmer's switch or CMD-PWR keyboard sequence, which brings up a debugger that the attacker can use to disable the lock.

Macintosh systems generate large ICMP datagrams in response to malformed datagrams, allowing them to be used as amplifiers in a flood attack.

"Multiple Users" Control Panel in Mac OS 9 allows Normal users to gain Owner privileges by removing the Users & Groups Data File, which effectively removes the Owner password and allows the Normal user to log in as the Owner account without a password.

App Bypass of Privacy Preferences in Apple Operating Systems

Sensitive User Data Leak in macOS Tahoe 26.3

This issue was addressed with improved data protection. This issue is fixed in macOS Tahoe 26.3. An app may be able to access sensitive user data.

macOS Privilege Escalation via Improper Symlink Handling

This issue was addressed with improved handling of symlinks. This issue is fixed in macOS Tahoe 26.3. An app may be able to gain root privileges.

Root Privilege Escalation via Malicious App on Apple Platforms

This issue was addressed with improved checks. This issue is fixed in iOS 26.3 and iPadOS 26.3, macOS Sequoia 15.7.4, macOS Tahoe 26.3, visionOS 26.3. A malicious app may be able to gain root privileges.

A logging issue was addressed with improved data redaction. This issue is fixed in macOS Tahoe 26.3. A malicious app may be able to read sensitive location information.

Denial of Service via Crafted Bluetooth Packets in Apple Operating Systems

A denial-of-service issue was addressed with improved validation. This issue is fixed in iOS 26.3 and iPadOS 26.3, macOS Tahoe 26.3, tvOS 26.3, visionOS 26.3, watchOS 26.3. An attacker in a privileged network position may be able to perform denial-of-service attack using crafted Bluetooth packets.

App Information Disclosure via Installed App Enumeration

A privacy issue was addressed with improved checks. This issue is fixed in iOS 18.7.5 and iPadOS 18.7.5, iOS 26.3 and iPadOS 26.3, macOS Sequoia 15.7.4, macOS Sonoma 14.8.4, macOS Tahoe 26.3, tvOS 26.3, visionOS 26.3, watchOS 26.3. An app may be able to identify what other apps a user has installed.
