X Fontserver for Truetype fonts (xfstt) 1.4 allows remote attackers to cause a denial of service and possibly execute arbitrary code via a (1) FS_QueryXExtents8 or (2) FS_QueryXBitmaps8 packet, and possibly other types of packets, with a large num_ranges value, which causes an out-of-bounds array access.
