[HIGH] adsys, juju-core, lxd vulnerabilities adsys, juju-core, lxd vulnerabilities USN-8089-1 fixed vulnerabilities in Go Networking. This update provides the corresponding update to code vendored in LXD, ADSys, and Juju Core. Original advisory details: Bahruz Jabiyev, Tommaso Innocenti, Anthony Gavazzi, Steven Sprecher, and Kaan Onarlioglu discovered that servers using Go Networking could hang during shutdown if preempted by a fatal error. An attacker could possibly use this to cause a denia

CVE-2026-33542 [MEDIUM] CVE-2026-33542: Incus is a system container and virtual machine manager Incus is a system container and virtual machine manager. Prior to version 6.23.0, a lack of validation of the image fingerprint when downloading from simplestreams image servers opens the door to image cache poisoning and under very narrow circumstances exposes other tenants to running attacker controlled images rather than the expected one. Version 6.23.0 patches the issue.
