Routinator exits on any error when accepting incoming HTTP or RTR connections, including ones it can recover from such as running out of file descriptors. This condition can be triggered maliciously by an attacker by opening a large number of connections to the HTTP or RTR server. This only affects users that make their HTTP or RTR server available to untrusted networks.

The remote Fedora 45 host has packages installed that are affected by multiple vulnerabilities as referenced in the FEDORA-2026-188f731254 advisory.

    Update `routinator` to the latest, pulling in updated dependencies (`rpki` and `syslog`), and switch     `fern` to using `syslog` 7 instead of 6 for this update, and loosen the `syslog` version bound for `ifcfg-     devname`.


    # v0.15.2     This release fixes a number of vulnerabilities and security issues identified by a security audit     performed by [X41 D-Sec] and financed by [Sovereign Tech Agency].

    **We advise all users to upgrade at their earliest convenience.**

    ## Security fixes

    * Changed how transient errors when accepting incoming HTTP and RTR connections are handled: instead of     exiting, a warning is printed and the error is ignored. ([#1099])

      This issue was assigned [CVE-2026-49232].

    * Extended the check for illegal path components in rsync URIs to also include the authority and module     parts. (via [rpki-rs#370])

      This fixes a path traversal vulnerability that has been assigned [CVE-2026-49233].

    * Fixed a panic when parsing certain AS numbers from strings. (via [rpki-rs#373])

      This fixes a vulnerability that has been assigned [CVE-2026-49234].

    * Upgraded quick-xml to at least 0.39.4 to fix a regression in XML parsing that may lead a panic on     certain crated XML files. (via [rpki-rs#372])

      This fixes a vulnerability that has been assigned [CVE-2026-49235].

    ## Improvements

    * Restricted trust anchor certificates downloaded via HTTP to the size given via the `max_object_size`     config option. ([#1090])
    * The `-e` and `--rsh` options will now be rejected in the `rsync-args` config option. Similarly,     Routinator will not start if the equivalent evironment variable `RSYNC_RSH` is set. ([#1091])

    ## Bug fixes

    * Set an RTR listener socket received via systemd to non-blocking. This fixes a panic in Tokio. ([#1081]     by [@MaxHearnden])
    * Fixed the `--rrdp-tcp-keepalive` to be a command line option rather than a command line argument.
    ([1085])

    ## Other changes

    * Support for Ubuntu Resolute Raccoon (26.04). ([#1095])

    # v0.15.1

    ## Bug fixes

    * Abort the optimistic initial run if there are no stored TA certificates for a TAL instead of succeeding     with an empty data set. ([#1071])
    * Undo `PrivateUsers` restriction in systemd unit files to allow user to run Routinator on privileged     ports. ([#1068])

    [#1068]: https://github.com/NLnetLabs/routinator/pull/1068     [#1071]: https://github.com/NLnetLabs/routinator/pull/1071

    # v0.15.0

    ## Breaking changes

    * Removed the `rrdp-keep-responses` feature. We suggest the use of an HTTP proxy such as [mitmproxy]     instead.

      This once and for all fixes [CVE-2023-39916] which returned again in release 0.14.0. ([#1055])
    * Messages about issues with repositories and publication points are now logged separately and by default     are only visible in the status HTTP server endpoints. The new `log-repository-issues` option can be used     to have these messages also written to the log. ([#1054])
    * Changed how server mode deals with broken or missing local exception files. Previously, Routinator would     just stop updating until they are fixed, leading to updates being stalled if the operator misses the error     messages. Now it will log a warning and keep using the previous set of local exceptions. When starting, it     will exit with an error message if there are broken or missing local exception files. ([#1060])
    * Changed the RRDP timeouts: introduced a new config variable `rrdp-read-timeout` that provides a timeout     for individual network operations (primarily: read from the server). Its default is 10 seconds. This     timeout is also used for connecting of no specific value is given, significantly speeding up validation     runs.

      In addition, the RRDP timeout was increased from 300 to 600 seconds to better deal with slow     transmission of large snapshots of some repositories. ([#1061])

    ## New

    * Added a quick initial run after starting the server which only uses stored data and aborts if any     required data hasnt been requested before to deal with configuration changes. This will shorten the     wait time for an initial data set when restarting Routinator. ([#1057])
    * Added support for SLURM v2 as output format which includes ASPA payload. ([#1021])
    * Changed refresh behaviour to better cope with short-lived objects. By default, Routinator will now wait     for the time defined by `refresh` even if objects expire earlier. The new `min-refresh` option can be used     to specify a short minimum refresh time if objects expire before the refresh time. If this value is set to     0, the old behaviour is restored. ([#1027])
    * The order in which manifest entries are processed is now randomized. ([#1041])
    * Reduced the overhead of storing RRDP snapshot downloads, significantly improving the snapshot update     times. ([#1035])
    * The `dump` command now prints the source directories of the data it dumps. ([#1045])
    * Added a `--update-after` option to the `vrps` subcommand that skips updating the local cache if the last     successful validation run was known to be less than a given number of minutes ago. ([#1049])
    * Error responses for API-related HTTP endpoints now contain JSON bodies. ([#1050])
    * The `/validity` HTTP server endpoint now accepts POST requests with a JSON body containing multiple     routes to be checked all at once. ([#1053])
    * Better protect against corrupted stored publication points by double checking cached manifest properties     against the actual manifest and discard the stored publication point if they mismatch.

      This fixes an issue where an accidentally or maliciously manipulated locally stored manifest could block     update of a legitimate new manifest which was reported by Zizhi Shang, Zhechao Lin, Jiahao Cao, Yangyang     Wang, Mingwei Xu of the Institute for Network Sciences and Cyberspace (INSC), Tsinghua University.

    ## Bug fixes

    * Fixed a crash if certain invalid character appear in a manifest file name by limiting the name to the     rules defined in [RFC9286]. This issue was reported by  Niklas Vogel of Goethe University Frankfurt and     ATHENE. ([rpki-rs#342])
    * Re-implemented RRDP client metrics based on the much simpler model used by RTRTR to fix recurring errors     in the metrics. ([#1039])
    * Changed the message logged when an RRDP update times out to actually say that. ([#1052])

    ## Other changes

    * Improved performance of file system operations on validate subcommand. ([#1043] by [@kawaemon])
    * Add package.homepage to Cargo.toml ([#1024])
    * Added building packages for RHEL 10 and Debian 13. ([#1034], [#1047])
    * Added building packages for ARMv6 and ARM64 for Debian Bookworm. ([#1036])
    * Added additional restrictions to the systemd unit files used in the various binary packages. ([#1056])
    * Upgrades various dependencies. ([#1004], [#1005], [#1006])

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.

The version of FreeBSD installed on the remote host is prior to tested version. It is, therefore, affected by a vulnerability as referenced in the b1c6c691-6a57-11f1-bf61-3c7c3fba4204 advisory.
