## Description

Integer overflow in the qtmd\_decompress function in libmspack 0.4 allows
remote attackers to cause a denial of service (hang) via a crafted CAB
file, which triggers an infinite loop.

### From the Ubuntu Security Team

It was discovered that cabextract incorrectly handled certain malformed CAB
files. An attacker could use this issue to cause cabextract to hang,
resulting in a denial of service.
