Beschreibung:
Victor Stinner hat eine Sicherheitslücke in FreeType gemeldet, die böswillige Personen ausnutzen können, um einen DoS (Denial of Service) zu verursachen oder potenziell eine Anwendung, die die Bibliothek verwendet zu kompromittieren.

Die Sicherheitslücke besteht in einem Fehler beim Parsen von fehlerhaften TTF-Fonts in src/truetype/ttgload.c und könnte ausgenutzt werden, wenn ein speziell präparierter TTF-Font verarbeitet wird

Die Sicherheitslücke wurde in Version 2.3.4 gemeldet. Andere Versionen können ebenfalls betroffen sein.
