medium Nessus Plugin ID 181204

Language:

Synopsis

The remote Fedora host is missing one or more security updates.

Description

The remote Fedora 37 host has a package installed that is affected by multiple vulnerabilities as referenced in the FEDORA-2023-40298f6951 advisory.

 Release notes for xrdp v0.9.23 (2023/08/31)

 General announcements

 - Running xrdp and xrdp-sesman on separate hosts is still supported by this release, but is now deprecated. This is not secure. A future v1.0 release will replace the TCP socket used between these processes with a Unix Domain Socket, and then cross-host running will not be possible.

 Security fixes

 - CVE-2023-40184: Improper handling of session establishment errors allows bypassing OS-level session restrictions (Reported by @gafusss)

 Bug fixes

 - Environment variables set by PAM modules are no longer restricted to around 250 characters (#2712)
 - X11 clipboard clients now no longer hang when requesting a clipboard format which isn't available (#2767)

 New features

 No new features in this release.
 Internal changes

 - Introduce release tarball generation script (#2703)
 - cppcheck version used for CI bumped to 2.11 (#2738)

 Known issues

 - On-the-fly resolution change requires the Microsoft Store version of Remote Desktop client but sometimes crashes on connect (#1869)
 - xrdp's login dialog is not relocated at the center of the new resolution after on-the-fly resolution change happens (#1867)

Tenable has extracted the preceding description block directly from the Fedora security advisory.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

Solution

Update the affected 1:xrdp package.
