HIGH Summary
The cabd_read_string function in mspack/cabd.c in libmspack 0.5alpha, as used in ClamAV 0.99.2 and other products, allows remote attackers to cause a denial of service (stack-based buffer over-read and application crash) via a crafted CAB file.

Common Attack Pattern Enumeration and Classification (CAPEC)
- Overread Buffers An adversary attacks a target by providing input that causes an application to read beyond the boundary of a defined buffer. This typically occurs when a value influencing where to start or stop reading is set to reflect positions outside of the valid memory location of the buffer. This type of attack may result in exposure of sensitive information, a system crash, or arbitrary code execution.
