In tt_face_colr_blend_layer of ttcolr.c, there is a possible remote code execution due to an integer overflow. This could lead to local escalation of privilege with no additional execution privileges needed. User interaction is not needed for exploitation.
AnalysisAI
Integer overflow in FreeType's COLR color-layer blending function (tt_face_colr_blend_layer in ttcolr.c) enables local privilege escalation across Android 14 through 17. A low-privileged app can deliver a maliciously crafted TrueType font containing a corrupted COLR table, triggering arithmetic overflow that corrupts heap memory and enables code execution in a higher-privileged system context. …
