Description Ganesh 2026-07-15 19:19:33 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.

Flameshot is powerful yet simple to use screenshot software. Prior to 14.0.0, the Open With feature wrote screenshots to a predictable temporary path and followed symlinks, creating a time-of-check to time-of-use race that allowed a local unprivileged attacker on the same machine to pre-plant a symlink and cause Flameshot to write PNG data through it, overwriting any file the victim user could write. This issue is fixed in version 14.0.0.

This bug appears to have been reported against 'rawhide' during the Fedora Linux 45 development cycle.
Changing version to 45.

Comment 2 Shawn W Dunn 2026-10-07 16:11:24 UTC

Rawhide, F45 and F44 already have the patched 14.x release shipping, with F43 scheduled for EOL next month, I'm closing.
