NVD Description

Note: Versions mentioned in the description apply only to the upstream clamav package and not the clamav package as distributed by Ubuntu. See How to fix? for Ubuntu:14.04 relevant fixed versions and status.

In mspack/cab.h in libmspack before 0.8alpha and cabextract before 1.8, the CAB block input buffer is one byte too small for the maximal Quantum block, leading to an out-of-bounds write.
