Comment 1 Aoife Moloney 2026-08-17 14:16:21 UTC
This bug appears to have been reported against 'rawhide' during the Fedora Linux 45 development cycle.
Changing version to 45.

Update on the current status of this tracker (which tracks 3 CVEs at once, for some reason...)

Seems (no for-certain confirmation yet on the upstream tracker) like CVE-2026-3632 might have been fixed already in https://gitlab.gnome.org/GNOME/libsoup/-/commit/167ef0c6817658c1a089c75c462482209e207db4, which is the fix for CVE-2026-1467, which was addressed in https://bugzilla.redhat.com/show_bug.cgi?id=2433180 and https://bugzilla.redhat.com/show_bug.cgi?id=2433177

CVE-2026-3633 has a proposed fix: https://gitlab.gnome.org/GNOME/libsoup/-/merge_requests/554

CVE-2026-3634 was fixed in https://gitlab.gnome.org/GNOME/libsoup/-/work_items/486, which is the fix for CVE-2026-1536, which was fixed in https://bugzilla.redhat.com/show_bug.cgi?id=2433838. The upstream tracker was closed to confirm this

Comment 3 Adrian Vovk 2026-10-27 01:38:19 UTC
Update on the current status of this tracker:

CVE-2026-3632 is still in unclear state. I've asked for clarification

CVE-2026-3633 has been fixed in 3.7.3+. f45/rawhide will thus get the fix when I run mclazy next. f44/f43 need https://gitlab.gnome.org/GNOME/libsoup/-/merge_requests/554 backported
