Ubuntu Security Notice USN-6927-1

Ubuntu Security Notice 6927-1 - Ziming Zhang discovered that the DRM driver for VMware Virtual GPU did not properly handle certain error conditions, leading to a NULL pointer dereference. A local attacker could possibly trigger this vulnerability to cause a denial of service. Gui-Dong Han discovered that the software RAID driver in the Linux kernel contained a race condition, leading to an integer overflow vulnerability. A privileged attacker could possibly use this to cause a denial of service.

GHSA-h9mq-f6q5-6c8m: GraphQL Java does not properly consider ExecutableNormalizedFields (ENFs) as part of preventing denial of service

GraphQL Java (aka graphql-java) before 21.5 does not properly consider ExecutableNormalizedFields (ENFs) as part of preventing denial of service via introspection queries. 20.9 and 19.11 are also fixed versions.

GHSA-cf56-g6w6-pqq2: Twisted vulnerable to HTML injection in HTTP redirect body

### Summary The `twisted.web.util.redirectTo` function contains an HTML injection vulnerability. If application code allows an attacker to control the redirect URL this vulnerability may result in Reflected Cross-Site Scripting (XSS) in the redirect response HTML body. ### Details Twisted’s `redirectTo` function generates an `HTTP 302 Redirect` response. The response contains an HTML body, built for exceptional cases where the browser doesn’t properly handle the redirect, allowing the user to click a link, navigating them to the specified destination. The function reflects the destination URL in the HTML body without any output encoding. ```python # https://github.com/twisted/twisted/blob/trunk/src/twisted/web/_template_util.py#L88 def redirectTo(URL: bytes, request: IRequest) -> bytes: # ---snip--- content = b""" <html> <head> <meta http-equiv=\"refresh\" content=\"0;URL=%(url)s\"> </head> <body bgcolor=\"#FFFFFF\" text=\"#000000\"> <a href=\"%(url)...
