Description

Gnome Fonts Viewer 3.34.0 contains a heap corruption vulnerability that allows attackers to trigger an out-of-bounds write by crafting a malicious TTF font file. Attackers can generate a specially crafted TTF file with an oversized pattern to exhaust memory through repeated malloc() calls and potentially crash the gnome-font-viewer process.
