Heap-based buffer overflow in the Lookup_MarkMarkPos function in the HarfBuzz module (harfbuzz-gpos.c), as used by Qt before 4.7.4 and Pango, allows remote attackers to cause a denial of service (crash) and possibly execute arbitrary code via a crafted font file. Desbordamiento de buffer de memoria dinámica en la función Lookup_MarkMarkPos del módulo HarfBuzz (harfbuzz-gpos.c), tal como se usa en Qt anteriores a 4.7.4 y Pango.
