Changes:
jetty9 (9.4.50-4+deb12u1) bookworm-security; urgency=high
.
* Team upload.
* The org.eclipse.jetty.servlets.CGI has been deprecated. It is potentially
unsafe to use it. The upstream developers of Jetty recommend to use Fast CGI
instead. See also CVE-2023-36479.
* Fix CVE-2023-26048:
Jetty is a java based web server and servlet engine. In affected versions
servlets with multipart support (e.g. annotated with `@MultipartConfig`)
that call `HttpServletRequest.getParameter()` or
`HttpServletRequest.getParts()` may cause `OutOfMemoryError` when the
client sends a multipart request with a part that has a name but no
filename and very large content. This happens even with the default
settings of `fileSizeThreshold=0` which should stream the whole part
content to disk.
* Fix CVE-2023-26049:
Nonstandard cookie parsing in Jetty may allow an attacker to smuggle
cookies within other cookies, or otherwise perform unintended behavior by
tampering with the cookie parsing mechanism.
* Fix CVE-2023-40167:
Prior to this version Jetty accepted the `+` character proceeding the
content-length value in a HTTP/1 header field. This is more permissive than
allowed by the RFC and other servers routinely reject such requests with
400 responses. There is no known exploit scenario, but it is conceivable
that request smuggling could result if jetty is used in combination with a
server that does not close the connection after sending such a 400
response.
* CVE-2023-36479:
Users of the CgiServlet with a very specific command structure may have the
wrong command executed. If a user sends a request to a
org.eclipse.jetty.servlets.CGI Servlet for a binary with a space in its
name, the servlet will escape the command by wrapping it in quotation
marks. This wrapped command, plus an optional command prefix, will then be
executed through a call to Runtime.exec. If the original binary name
provided by the user contains a quotation mark followed by a space, the
resulting command line will contain multiple tokens instead of one.
* Fix CVE-2023-41900:
Jetty is vulnerable to weak authentication. If a Jetty
`OpenIdAuthenticator` uses the optional nested `LoginService`, and that
`LoginService` decides to revoke an already authenticated user, then the
current request will still treat the user as authenticated. The
authentication is then cleared from the session and subsequent requests
will not be treated as authenticated. So a request on a previously
authenticated session could be allowed to bypass authentication after it
had been rejected by the `LoginService`. This impacts usages of the
jetty-openid which have configured a nested `LoginService` and where that
`LoginService` is capable of rejecting previously authenticated users.
