Ubuntu Security Notice 7089-3 - Chenyuan Yang discovered that the USB Gadget subsystem in the Linux kernel did not properly check for the device to be enabled before writing. A local attacker could possibly use this to cause a denial of service. Several security issues were discovered in the Linux kernel. An attacker could possibly use these to compromise the system.

Ubuntu Security Notice 7088-3 - Ziming Zhang discovered that the VMware Virtual GPU DRM driver in the Linux kernel contained an integer overflow vulnerability. A local attacker could use this to cause a denial of service. Several security issues were discovered in the Linux kernel. An attacker could possibly use these to compromise the system.

Ubuntu Security Notice 7093-1 - It was discovered that Werkzeug incorrectly handled multiple form submission requests. A remote attacker could possibly use this issue to cause Werkzeug to consume resources, leading to a denial of service.

Ubuntu Security Notice 7092-1 - It was discovered that mpg123 incorrectly handled certain mp3 files. If a user or automated system were tricked into opening a specially crafted mp3 file, a remote attacker could use this issue to cause mpg123 to crash, resulting in a denial of service, or possibly execute arbitrary code.

Ubuntu Security Notice 7091-1 - It was discovered that Ruby incorrectly handled parsing of an XML document that has specific XML characters in an attribute value using REXML gem. An attacker could use this issue to cause Ruby to crash, resulting in a denial of service. This issue only affected in Ubuntu 22.04 LTS and Ubuntu 24.04 LTS. It was discovered that Ruby incorrectly handled parsing of an XML document that has many entity expansions with SAX2 or pull parser API. An attacker could use this issue to cause Ruby to crash, resulting in a denial of service.

Ubuntu Security Notice 7083-1 - It was discovered that OpenJPEG incorrectly handled certain memory operations when using the command line "-ImgDir" in a directory with a large number of files, leading to an integer overflow vulnerability. An attacker could potentially use this issue to cause a denial of service. This issue only affected Ubuntu 16.04 LTS, Ubuntu 18.04 LTS, Ubuntu 20.04 LTS and Ubuntu 22.04 LTS. It was discovered that OpenJPEG incorrectly handled decompressing certain .j2k files in sycc420_to_rgb, leading to a heap-based buffer overflow vulnerability. If a user or automated system were tricked into opening a specially crafted file, an attacker could possibly use this issue to execute arbitrary code.

### Summary The various header-related Refit attributes (Header, HeaderCollection and Authorize) are vulnerable to CRLF injection. ### Details The way HTTP headers are added to a request is via the `HttpHeaders.TryAddWithoutValidation` method: <https://github.com/reactiveui/refit/blob/258a771f44417c6e48e103ac921fe4786f3c2a1e/Refit/RequestBuilderImplementation.cs#L1328> This method does not check for CRLF characters in the header value. This means that any headers added to a refit request are vulnerable to CRLF-injection. In general, CRLF-injection into a HTTP header (when using HTTP/1.1) means that one can inject additional HTTP headers or smuggle whole HTTP requests. ### PoC The below example code creates a console app that takes one command line variable (a bearer token) and then makes a request to some status page with the provided token inserted in the "Authorization" header: ```c# using Refit; internal class Program { private static void Main(string[] args) { ...
