When rendering with headless builds, show an error instead of crashing. Previously GPU_backend_init was called indirectly from DRW_opengl_context_create, a new function is now called from the window manager (GPU_backend_init_once), so it's possible to check if the GPU has a back-end. This also disables the bgl Python module when building WITH_HEADLESS.

Ubuntu Security Notice 5569-1 - Xiang Li discovered that Unbound incorrectly handled delegation caching. A remote attacker could use this issue to keep rogue domain names resolvable long after they have been revoked.

upsMonitor in ViewPower (aka ViewPowerHTML) 1.04-21012 through 1.04-21353 has insecure permissions for the service binary that enable an Authenticated User to modify files, allowing for privilege escalation.

Ubuntu Security Notice 5568-1 - Several security issues were discovered in the WebKitGTK Web and JavaScript engines. If a user were tricked into viewing a malicious website, a remote attacker could exploit a variety of issues related to web browser security, including cross-site scripting attacks, denial of service attacks, and arbitrary code execution.

A buffer overflow in the FTcpListener thread in The Isle Evrima (the dedicated server on Windows and Linux) 0.9.88.07 before 2022-08-12 allows a remote attacker to crash any server with an accessible RCON port, or possibly execute arbitrary code.

There is an out-of-bounds write in checkType located in etc.c in w3m 0.5.3. It can be triggered by sending a crafted HTML file to the w3m binary. It allows an attacker to cause Denial of Service or possibly have unspecified other impact.

Ubuntu Security Notice 5567-1 - Zhenpeng Lin discovered that the network packet scheduler implementation in the Linux kernel did not properly remove all references to a route filter before freeing it in some situations. A local attacker could use this to cause a denial of service or execute arbitrary code. It was discovered that the netfilter subsystem of the Linux kernel did not prevent one nft object from referencing an nft set in another nft table, leading to a use-after-free vulnerability. A local attacker could use this to cause a denial of service or execute arbitrary code.
