lrzsz before version 0.12.21~rc can leak information to the receiving side due to an incorrect length check in the function zsdata that causes a size_t to wrap around.
The product performs a calculation that can produce an integer overflow or wraparound when the logic assumes that the resulting value will always be larger than the original value. This occurs when an integer value is incremented to a value that is too large to store in the associated representation. When this occurs, the value may become a very small or negative number.
