Beskrivelse:
Victor Stinner har rapporteret en sårbarhed i FreeType, som kan udnyttes af ondsindede personer til at udføre et DoS (Denial of Service) og potentielt kompromittere en applikation, der benytter biblioteket.

Sårbarheden skyldes en fejl under fortolkningen af TTF fonte i src/truetype/ttgload.c og kan udnyttes via en specielt udformet TTF-font.

Sårbarheden er rapporteret i version 2.3.4, men andre versioner kan også være berørte.
