### Impact When using the recommended "best-effort" mode, Go-Landlock did not restrict the TCP bind() and connect() operations any more when they were requested. This affects Go-Landlock users to whom both of the following conditions apply: * They use Landlock rulesets that are supposed to restrict networking (through `landlock.V4`, `landlock.V5`, or self-configured). * These Landlock rulesets are used in best-effort mode. Typically, affected code uses the Go-Landlock API like this (the crucial part being the combination of `V4`/`V5` and `.BestEffort()`): ``` err := landlock.V5.BestEffort().Restrict(...) ``` * This is a bug in the Go-Landlock library and does not affect programs that use Landlock via C or other language bindings. * The bug only affects networking restrictions. File system restrictions continue to work as expected. ### Patches Patched in: https://github.com/landlock-lsm/go-landlock/commit/fb3ad845df462d013f9c8a965c496617c6a5778b Users should upgrade to: v0.0.0-202...

ABB Cylon Aspect version 3.07.02 suffers from a vulnerability that allows an unauthenticated attacker to enable or disable the SSH daemon by sending a POST request to sshUpdate.php with a simple JSON payload. This can be exploited to start the SSH service on the remote host without proper authentication, potentially enabling unauthorized access or stop and deny service access.

Debian Linux Security Advisory 5788-1 - Damien Schaeffer discovered a use-after-free in the Mozilla Firefox web browser, which could result in the execution of arbitrary code.

The BMS/BAS controller suffers from a vulnerability that allows an unauthenticated attacker to enable or disable the SSH daemon by sending a POST request to sshUpdate.php with a simple JSON payload. This can be exploited to start the SSH service on the remote host without proper authentication, potentially enabling unauthorized access or stop and deny service access.

CVE description: Authd, through version 0.3.6, did not sufficiently randomize user IDs to prevent collisions. A local attacker who can register user names could spoof another user's ID and gain their privileges. ----- original report ----- # Cause authd assigns user IDs as a pure function of the user name. Moreover, the set of UIDs is much too small for pseudo-random assignment to work: the birthday bound predicts random collisions will occur with probability 50% after only 54 562 IDs were assigned. `authd` only checks for uniqueness [within its local cache](https://github.com/ubuntu/authd/blob/4946962aa4ac6e5b7d2b53503026659581c73907/internal/users/cache/update.go#L67-L71), which - may be inconsistent across multiple systems within the same domain ; - may be purged, due to being stored in `/var/cache` ; - automatically removes entries of users who have not logged into that specific system within the last 6 months. The current `GenerateID` method, authored in September 2024 (commi...

Microsoft today released security updates to fix at least 117 security holes in Windows computers and other software, including two vulnerabilities that are already seeing active attacks. Also, Adobe plugged 52 security holes across a range of products, and Apple has addressed a bug in its new macOS 15 "Sequoia" update that broke many cybersecurity tools.

The two vulnerabilities that Microsoft reports have been actively exploited in the wild and are publicly known are both rated as only being of “moderate” severity.

A little-known threat actor tracked as GoldenJackal has been linked to a series of cyber attacks targeting embassies and governmental organizations with an aim to infiltrate air-gapped systems using two disparate bespoke toolsets. Victims included a South Asian embassy in Belarus and a European Union government (E.U.) organization, Slovak cybersecurity company ESET said. "The ultimate goal of
