Ubuntu Security Notice 7088-2 - 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.

### 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) { ...

Sysax Multi Server version 6.9.9 suffers from an SSH related denial of service vulnerability.

Ubuntu Security Notice 7090-1 - 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 7076-2 - Several security issues were discovered in the Linux kernel. An attacker could possibly use these to compromise the system.

Ubuntu Security Notice 7021-5 - Several security issues were discovered in the Linux kernel. An attacker could possibly use these to compromise the system.

Ubuntu Security Notice 7086-1 - Multiple security issues were discovered in Firefox. If a user were tricked into opening a specially crafted website, an attacker could potentially exploit these to cause a denial of service, obtain sensitive information across domains, or execute arbitrary code.
