Summary

The Gnome Pango library version 1.42 and later suffers from a heap-based buffer overflow, which is triggered when an application processes invalid UTF-8 strings through functions like pango_itemize. This vulnerability lies in the pango_log2vis_get_embedding_levels function, specifically in the misassignment of characters and loop condition management. An attacker can exploit this weakness to execute arbitrary code, posing a significant risk to applications relying on Pango.
