Description of problem:
Cabextract goes into an infinite loop when trying to expand a special crafted .cab file as attached. This seems to originate in a bug in the embeded libmspack.
Contrary to the report, clamav doesn't show this behavior.
See bug # 15155
This causes a security issue in amavisd and can cause a DoS attack.
