GNOME's help viewer, Yelp, has received an update to version 49.1. This release addresses a newly identified security vulnerability described as "a possible Flatpak sandbox escape vector." The fix is intended to maintain the integrity of the Flatpak sandboxing mechanism, which isolates applications to prevent unauthorized access to the underlying system. This ensures the help viewer operates within its designated security boundaries when run as a Flatpak application. This follows a previous security issue last year where Yelp was impacted by a vulnerability allowing arbitrary file reads.
