Description Vladimir Vasilev 2026-09-23 12:04:20 UTC
Disclaimer: Community trackers are created by Red Hat Product Security team on a best effort basis. Package maintainers are required to ascertain if the flaw indeed affects their package, before starting the update process.

An issue in CrossWire Xiphos <= 4.3.2 allows a local attacker to execute arbitrary code via the src/main/url.cc and src/gtk/menu_popup.c components

I'll look into fixing this issue this Saturday if no one beats me to it.

Comment 2 greg.hellings 2026-09-25 01:42:03 UTC
I'm fairly sure this is already fixed in 4.4.0. Several such fixes for "bugs" were in that release, which I already packaged for Rawhide. So it should just be as simple as pulling that into the desired release branch. As I don't have a desktop Fedora install anymore I can't very well test those builds so I refrain from pulling new releases into existing Fedora versions.

But a merge from rawhide with a build and Bodhi fix ought to accomplish what you need.

Comment 3 Aaron Rainbolt 2026-09-25 05:00:30 UTC
I'm a little rusty on what Fedora's policies are around pulling new versions into existing releases (most of my work is in Debian/Ubuntu where the process is "backport the patch", but I know Fedora operates somewhat differently). That sounds like it will probably work though. Thanks for the tip!

Comment 4 Aaron Rainbolt 2026-09-28 05:19:14 UTC
I embarrassingly forgot this over the weekend. I've gotten a packaging VM set up again, I'll try to remember to do this Monday morning.

Comment 5 Aaron Rainbolt 2026-09-30 23:56:03 UTC
Looking at Fedora's packaging policies, I don't think I can do a full version backport. I have backported the fixing commit however (https://github.com/crosswire/xiphos/pull/1314/changes/68bbe3063b601537d1e505dd1a4560d51811a9e0), and have verified that it builds in mockbuild for both F44 and F43. I don't have time to finish testing today, but will get to it as soon as reasonably possible and hopefully publish updates not too long after.
