Tor Browser through 10.5.6 and 11.x through 11.0a4 allows a correlation attack that can compromise the privacy of visits to v2 onion addresses. Exact timestamps of these onion-service visits are logged locally, and an attacker might be able to compare them to timestamp data collected by the destination server (or collected by a rogue site within the Tor network).

An issue was discovered in certain Apple products. iOS before 10.1 is affected. The issue involves the "Contacts" component, which does not prevent an app's Address Book access after access revocation.

Siri in Apple iOS before 7.1.2 allows physically proximate attackers to bypass an intended lock-screen passcode requirement, and read a contact list, via a Siri request that refers to a contact ambiguously.

This issue is fixed in iOS 15.4 and iPadOS 15.4. A person with physical access may be able to view and modify the carrier account information and settings from the lock screen.

iChat in Apple Mac OS X 10.4.11 allows network-adjacent remote attackers to automatically initiate a video connection to another user via unknown vectors.

The issue was addressed with improved permissions logic. This issue is fixed in iTunes for Windows 12.10.4. A user may gain access to protected parts of the file system.

The Emergency Dialer screen in the Passcode Lock implementation in Apple iOS before 6 does not properly limit the dialing methods, which allows physically proximate attackers to bypass intended access restrictions and make FaceTime calls through Voice Dialing, or obtain sensitive contact information by attempting to make a FaceTime call and reading the contact suggestions.

A permissions issue was addressed with additional restrictions. This issue is fixed in macOS Sonoma 14.6, macOS Monterey 12.7.6, macOS Ventura 13.6.8. An app may be able to modify protected parts of the file system.

An issue was discovered in Samsung Magician 8.0.0 on macOS. Because symlinks are used during the installation process, an attacker can escalate privileges via arbitrary file permission writes. (The attacker must already have user privileges, and an administrator password must be entered during the program installation stage for privilege escalation.)

crontab.c in crontab in FreeBSD and Apple Mac OS X allows local users to (1) determine the existence of arbitrary files via a symlink attack on a /tmp/crontab.XXXXXXXXXX temporary file and (2) perform MD5 checksum comparisons on arbitrary pairs of files via two symlink attacks on /tmp/crontab.XXXXXXXXXX temporary files.

CUPS on Mandriva Linux 2008.0, 2008.1, 2009.0, Corporate Server (CS) 3.0 and 4.0, and Multi Network Firewall (MNF) 2.0 allows local users to overwrite arbitrary files via a symlink attack on the /tmp/pdf.log temporary file.

Apple Safari 3.2.1 (aka AppVer 3.525.27.1) on Windows allows remote attackers to cause a denial of service (infinite loop or access violation) via a link to an http URI in which the authority (aka hostname) portion is either a (1) . (dot) or (2) .. (dot dot) sequence.

A vulnerability in the London Trust Media Private Internet Access (PIA) VPN Client v82 for Linux and macOS could allow an authenticated, local attacker to overwrite arbitrary files. The openvpn_launcher binary is setuid root. This binary supports the --log option, which accepts a path as an argument. This parameter is not sanitized, which allows a local unprivileged user to overwrite arbitrary files owned by any user on the system, including root. This creates a denial of service condition and possible data loss if leveraged by a malicious local user.

Arbitrary File Overwrite in Eclipse JGit <= 6.6.0 In Eclipse JGit, all versions <= 6.6.0.202305301015-r, a symbolic link present in a specially crafted git repository can be used to write a file to locations outside the working tree when this repository is cloned with JGit to a case-insensitive filesystem, or when a checkout from a clone of such a repository is performed on a case-insensitive filesystem. This can happen on checkout (DirCacheCheckout), merge (ResolveMerger via its WorkingTreeUpdater), pull (PullCommand using merge), and when applying a patch (PatchApplier). This can be exploited for remote code execution (RCE), for instance if the file written outside the working tree is a git filter that gets executed on a subsequent git command. The issue occurs only on case-insensitive filesystems, like the default filesystems on Windows and macOS. The user performing the clone or checkout must have the rights to create symbolic links for the problem to occur, and symbolic links must be enabled in the git configuration. Setting git configuration option core.symlinks = false before checking out avoids the problem. The issue was fixed in Eclipse JGit version 6.6.1.202309021850-r and 6.7.0.202309050840-r, available via Maven Central https://repo1.maven.org/maven2/org/eclipse/jgit/  and repo.eclipse.org https://repo.eclipse.org/content/repositories/jgit-releases/ . A backport is available in 5.13.3 starting from 5.13.3.202401111512-r. The JGit maintainers would like to thank RyotaK for finding and reporting this issue.

A vulnerability in the London Trust Media Private Internet Access (PIA) VPN Client v0.9.8 beta (build 02099) for macOS could allow an authenticated, local attacker to overwrite arbitrary files. When the client initiates a connection, the XML /tmp/pia-watcher.plist file is created. If the file exists, it will be truncated and the contents completely overwritten. This file is removed on disconnect. An unprivileged user can create a hard or soft link to arbitrary files owned by any user on the system, including root. This creates a denial of service condition and possible data loss if leveraged by a malicious local user.
