Descriptions
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. Permite a atacantes remotos provocar una denegación de servicio (caída) y posiblemente ejecutar código arbitrario a través de un archivo de fuentes modificado.
Qt is a software toolkit that simplifies the task of writing and maintaining GUI applications for the X Window System. HarfBuzz is an OpenType text shaping engine. A buffer overflow flaw was found in the harfbuzz module in Qt. If a user loaded a specially-crafted font file with an application linked against Qt, it could cause the application to crash or, possibly, execute arbitrary code with the privileges of the user running the application. A buffer overflow flaw was found in the way Qt handled certain gray-scale image files. If a user loaded a specially-crafted gray-scale image file with an application linked against Qt, it could cause the application to crash or, possibly, execute arbitrary code with the privileges of the user running the application.
