Descriptions

The chmd_init_decomp function in chmd.c in libmspack before 0.5 does not properly validate the reset interval, which allows remote attackers to cause a denial of service (divide-by-zero error and application crash) via a crafted CHM file.

La función chmd_init_decomp en chmd.c en libmspack anterior a 0.5 no valida correctamente el intervalo de restablecimiento, lo que permite a atacantes remotos causar una denegación de servicio (error de dividir por cero y caída de aplicación) a través de un fichero CHM manipulado.
