Description OSIDB Bzimport 2025-05-21 03:21:35 UTC
Once gnome-remote-desktop is listening for RDP connections, an unauthenticated attacker can exhaust system resources and crash the process repeatedly. In fact, there is some sort of resource leak that after many attacks, will result in gnome-remote-desktop no longer being able to open files even after it is restarted via systemd.

Do you have more inforamtion on this issue? Any insights? The reference is quite vague at this point in time.

Sorry, I confused this with bug #2365232. This issue is different and I don't know anything yet. It has not been reported to GNOME Security.

This bug is only two days old, though. I guess we'll have more information soon.

Comment 6 Michael Catanzaro 2025-06-12 21:20:02 UTC
We are still missing an upstream bug report with details about this bug. I know we have the info within Red Hat, but if we can't get the info into an upstream bug report, then I'll need to dispute the CVE.

Hi, Jonas, do you have enough info to create an upstream bug report for this? Or do we need Product Security to help with this?

Since the CVE was published, I went and did a merge request directly, without dealing with any security related procedures. See https://gitlab.gnome.org/GNOME/gnome-remote-desktop/-/merge_requests/321.

Hi Jonas, e c

I'm trying to understand more about this issue. Is there any way to test or reproduce this issue? That would be really helpful to test. 

Thanks

I don't have a public reproducer to share, but using a RDP fuzzer that tries to connect many times per second throwing garbage at the RDP socket could cause sporadic problems with file descriptor leaks, that eventually hit the open file descriptor limit causing the server to abort.
