type42/t42parse.c in FreeType before 2.5.4 does not consider that scanning can be incomplete without triggering an error, which allows remote attackers to cause a denial of service (use-after-free) or possibly have unspecified other impact via a crafted Type42 font.
The _bdf_parse_glyphs function in bdf/bdflib.c in FreeType before 2.5.4 does not properly handle a missing ENDCHAR record, which allows remote attackers to cause a denial of service (NULL pointer dereference) or possibly have unspecified other impact via a crafted BDF font.
The tt_face_load_kern function in sfnt/ttkern.c in FreeType before 2.5.4 enforces an incorrect minimum table length, which allows remote attackers to cause a denial of service (out-of-bounds read) or possibly have unspecified other impact via a crafted TrueType font.
The tt_face_load_hdmx function in truetype/ttpload.c in FreeType before 2.5.4 does not establish a minimum record size, which allows remote attackers to cause a denial of service (out-of-bounds read) or possibly have unspecified other impact via a crafted TrueType font.
