Summary:	The remote host is missing an update for the Debian 'twisted' package(s) announced via the DLA-2927-1 advisory.
Description:	Summary: The remote host is missing an update for the Debian 'twisted' package(s) announced via the DLA-2927-1 advisory. Vulnerability Insight: It was discovered that Twisted, a Python event-based framework for internet applications, is affected by HTTP request splitting vulnerabilities, and may expose sensitive data when following redirects. An attacker may bypass validation checks and retrieve credentials. CVE-2020-10108 HTTP request splitting vulnerability. When presented with two content-length headers, it ignored the first header. When the second content-length value was set to zero, the request body was interpreted as a pipelined request. CVE-2020-10109 HTTP request splitting vulnerability. When presented with a content-length and a chunked encoding header, the content-length took precedence and the remainder of the request body was interpreted as a pipelined request. CVE-2022-21712 Twisted exposes cookies and authorization headers when following cross-origin redirects. This issue is present in the `twisted.web.RedirectAgent` and `twisted.web.BrowserLikeRedirectAgent` functions. For Debian 9 stretch, these problems have been fixed in version 16.6.0-2+deb9u1.
