Ubuntu Security Notice 6548-2 - It was discovered that Spectre-BHB mitigations were missing for Ampere processors. A local attacker could potentially use this to expose sensitive information. It was discovered that the USB subsystem in the Linux kernel contained a race condition while handling device descriptors in certain situations, leading to a out-of-bounds read vulnerability. A local attacker could possibly use this to cause a denial of service.

Apple Security Advisory 12-11-2023-4 - macOS Sonoma 14.2 addresses code execution, out of bounds read, and spoofing vulnerabilities.

Ubuntu Security Notice 6549-2 - It was discovered that the USB subsystem in the Linux kernel contained a race condition while handling device descriptors in certain situations, leading to a out-of-bounds read vulnerability. A local attacker could possibly use this to cause a denial of service. Lin Ma discovered that the Netlink Transformation subsystem in the Linux kernel did not properly initialize a policy data structure, leading to an out-of-bounds vulnerability. A local privileged attacker could use this to cause a denial of service or possibly expose sensitive information.

### Summary When parsing the attributes passed to a `use` tag inside an svg document, we can cause the system to go to an infinite recursion. Depending on the system configuration and attack pattern this could exhaust the memory available to the executing process and/or to the server itself. ### Details Inside `Svg\Tag\UseTag::before`, php-svg-lib parses the attributes passed to an `use` tag inside an svg document. When it finds a `href` or `xlink:href`, it will try to retrieve the object representing this tag: ``` $link = $attributes["href"] ?? $attributes["xlink:href"]; $this->reference = $document->getDef($link); if ($this->reference) { $this->reference->before($attributes); } ``` `$document->getDef` is implemented as follow: ``` public function getDef($id) { $id = ltrim($id, "#"); return isset($this->defs[$id]) ? $this->defs[$id] : null; } ``` _Note:_ the `$id` in the above method is actually the _link_ being used in `use` tag. This part is important, because thi...
