Descriptions

chmextract.c in the chmextract sample program, as distributed with libmspack before 0.8alpha, does not protect against absolute/relative pathnames in CHM files, leading to Directory Traversal. NOTE: the vendor disputes that this is a libmspack vulnerability, because chmextract.c was only intended as a source-code example, not a supported application

** EN DISPUTA ** chmextract.c en el programa de muestra chmextract, tal y como se distribuye en libmspack en versiones anteriores a la 0.8alpha, no protege contra nombres de ruta absoluta/relativa en archivos CHM, lo que conduce a un salto de directorio. NOTA: el fabricante discute que esto sea una vulnerabilidad en libmspack, ya que chmextract.c solo se diseñó como ejemplo de código abierto, no una aplicación soportada.
