### Impact The 19.0.0 release of Wasmtime contains a regression introduced during its development which can lead to a guest WebAssembly module causing a panic in the host runtime. A valid WebAssembly module, when executed at runtime, may cause this panic. The panic in question is caused when a WebAssembly module issues a `table.*` instruction which uses a dropped element segment with a table that also has an `externref` type. This causes Wasmtime to erroneously use an empty function segment instead of an empty externref segment to perform this operation. This mismatch in types causes a panic in Wasmtime when it's asserted that an externref table is only viewed as externrefs. This regression was introduced during the development of the 19.0.0 release and only affects the 19.0.0 release. This panic requires the `reference-types` WebAssembly feature to be enabled, and it is enabled by default. Toolchains are not known to generate this pattern by default so it's likely a module would nee...

### Impact In code which applies _un-sanitized string values into metric names or labels_, like this: ```swift let lang = try? request.query-get(String.self, at: "lang") Counter ( label: "language", dimensions: [("lang", lang ?? "unknown" )] ) ``` an attacker could make use of this and send a `?lang` query parameter containing newlines, `}` or similar characters which can lead to the attacker taking over the exported format -- including creating unbounded numbers of stored metrics, inflating server memory usage, or causing "bogus" metrics. ### Patches The default strategy to sanitize labels was moved deeper into the library, preventing illegal characters from appearing in name, label keys and values. Metric names and label names are now validated against the following requirement: `[a-zA-Z_:][a-zA-Z0-9_:]*` (for metric names) and `[a-zA-Z_][a-zA-Z0-9_]*` (for metric label names). Label values are not validated as they are allowed to contain any unicode characters. Developers...

### Impact All versions of ArgoCD starting from v2.4 have a bug where the ArgoCD repo-server component is vulnerable to a Denial-of-Service attack vector. Specifically, it's possible to crash the repo server component through an out of memory error by pointing it to a malicious Helm registry. The loadRepoIndex() function in the ArgoCD's helm package, does not limit the size nor time while fetching the data. It fetches it and creates a byte slice from the retrieved data in one go. If the registry is implemented to push data continuously, the repo server will keep allocating memory until it runs out of it. ### Patches A patch for this vulnerability has been released in the following Argo CD versions: v2.10.5 v2.9.10 v2.8.14 ### For more information If you have any questions or comments about this advisory: Open an issue in [the Argo CD issue tracker](https://github.com/argoproj/argo-cd/issues) or [discussions](https://github.com/argoproj/argo-cd/discussions) Join us on [Slack](https...

Debian Linux Security Advisory 5648-1 - Security issues were discovered in Chromium, which could result in the execution of arbitrary code, denial of service or information disclosure.

Ubuntu Security Notice 6707-4 - Lonial Con discovered that the netfilter subsystem in the Linux kernel did not properly handle element deactivation in certain cases, leading to a use-after-free vulnerability. A local attacker could use this to cause a denial of service or possibly execute arbitrary code. Notselwyn discovered that the netfilter subsystem in the Linux kernel did not properly handle verdict parameters in certain cases, leading to a use- after-free vulnerability. A local attacker could use this to cause a denial of service or possibly execute arbitrary code.

Ubuntu Security Notice 6704-4 - It was discovered that the NVIDIA Tegra XUSB pad controller driver in the Linux kernel did not properly handle return values in certain error conditions. A local attacker could use this to cause a denial of service. Quentin Minster discovered that the KSMBD implementation in the Linux kernel did not properly handle session setup requests. A remote attacker could possibly use this to cause a denial of service.

Red Hat Security Advisory 2024-1570-03 - Updated images are now available for Red Hat Advanced Cluster Security. Issues addressed include a denial of service vulnerability.
