Ubuntu Security Notice 6775-2 - Zheng Wang discovered that the Broadcom FullMAC WLAN driver in the Linux kernel contained a race condition during device removal, leading to a use- after-free vulnerability. A physically proximate attacker could possibly use this to cause a denial of service. Several security issues were discovered in the Linux kernel. An attacker could possibly use these to compromise the system.

### Summary During checkout, gitoxide does not verify that paths point to locations in the working tree. A specially crafted repository can, when cloned, place new files anywhere writable by the application. ### Details Although `gix-worktree-state` checks for collisions with existing files, it does not itself check if a path is really in the working tree when performing a checkout, nor do the path checks in `gix-fs` and `gix-worktree` prevent this. Cloning an untrusted repository containing specially crafted tree or blob names will create new files outside the repository, or inside the repository or a submodule's `.git` directory. The simplest cases are: - A tree named `..` to traverse upward. This facilitates arbitrary code execution because files can be placed in one or more locations where they are likely to be executed soon. - A tree named `.git` to enter a `.git` directory. This facilitates arbitrary code execution because hooks can be installed. A number of alternatives tha...

Apple and the satellite-based broadband service Starlink each recently took steps to address new research into the potential security and privacy implications of how their services geo-locate devices. Researchers from the University of Maryland say they relied on publicly available data from Apple to track the location of billions of devices globally -- including non-Apple devices like Starlink systems -- and found they could use this data to monitor the destruction of Gaza, as well as the movements and in many cases identities of Russian and Ukrainian troops.

Arm Mali versions since r45p0 suffer from a broken KBASE_USER_BUF_STATE_* state machine for userspace mappings that can lead to a use-after-free condition.

A WIRED investigation found thousands of Eventbrite posts selling escort services and drugs like Xanax and oxycodone—some of which the company’s algorithm recommended alongside addiction recovery events.

Minder engine is susceptible to a denial of service from memory exhaustion that can be triggered from maliciously created templates. Minder engine uses templating to generate strings for various use cases such as URLs, messages for pull requests, descriptions for advisories. In some cases can the user control both the template and the params for it, and in a subset of these cases, Minder reads the generated template entirely into memory. When Minders templating meets both of these conditions, an attacker is able to generate large enough templates that Minder will exhaust memory and crash. One of these places is the REST ingester: https://github.com/stacklok/minder/blob/daccbc12e364e2d407d56b87a13f7bb24cbdb074/internal/engine/ingester/rest/rest.go#L115-L123 With control over both endpoint and `retp` on the following line: https://github.com/stacklok/minder/blob/daccbc12e364e2d407d56b87a13f7bb24cbdb074/internal/engine/ingester/rest/rest.go#L121 … an attacker can make Minder generat...

The service offered by Pusher provides "private" channels with an authentication mechanism that restricts subscription access. The decision on allowing subscriptions to private channels is delegated to customers, who implement an authentication endpoint. End-users request a token from this endpoint to join a specific channel. The token is an HMAC signature of the end-user's connection ID (socket_id) and the desired channel. The issue arises from a lack of validation in the libraries provided to customers. This vulnerability allows a malicious end-user to submit a malformed socket_id field, leading the customer to unknowingly sign a string. This signed string grants access to a different private channel than the one the end-user is ostensibly requesting. Consequently, a malicious end-user, with permission to subscribe to one private channel, can forge permission for any private channel owned by the same customer. Additionally, the HTTP API is secured by requiring a signature with each...
