Description:	Summary: The remote host is missing an update for the Debian 'ruby-sinatra' package(s) announced via the DLA-3264-1 advisory. Vulnerability Insight: It was discovered that there was a potential reflected file download (RFD) vulnerability in ruby-sinatra, a Ruby library for writing HTTP applications. A Content-Disposition HTTP header was being incorrectly derived from a potentially user-supplied filename. CVE-2022-45442 Sinatra is a domain-specific language for creating web applications in Ruby. An issue was discovered in Sinatra 2.0 before 2.2.3 and 3.0 before 3.0.4. An application is vulnerable to a reflected file download (RFD) attack that sets the Content-Disposition header of a response when the filename is derived from user-supplied input. Version 2.2.3 and 3.0.4 contain patches for this issue. For Debian 10 Buster, this problem has been fixed in version 2.0.5-4+deb10u2. We recommend that you upgrade your ruby-sinatra packages.
