Buffer overflow in the zi_short function in zipinfo.c in Info-Zip UnZip 6.0 allows remote attackers to cause a denial of service (crash) via a large compression method value in the central directory file header.
The product performs operations on a memory buffer, but it reads from or writes to a memory location outside the buffer's intended boundary. This may result in read or write operations on unexpected memory locations that could be linked to other variables, data structures, or internal program data.
