CVE-2014-9675

bdf/bdflib.c en FreeType anterior a 2.5.4 identifica los nombres de propiedades con solamente verificar que una subcadena inicial esté presente, lo que permite a atacantes remotos descubrir valores de punteros de la memoria dinámica y evadir el mecanismo de protección ASLR a través de una fuente BDF manipulada.

The tt_sbit_decoder_load_image function in sfnt/ttsbit.c in FreeType before 2.5.4 does not properly check for an integer overflow, which allows remote attackers to cause a denial of service (out-of-bounds read) or possibly have unspecified other impact via a crafted OpenType 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 or possibly have unspecified other impact via a crafted TrueType 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 or possibly have unspecified other impact via a crafted TrueType font. Various other issues have also been addressed.
