DISPUTED 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.
