Description

libmikmod before 3.3.14 contains an integer overflow vulnerability in DSM_Load() in load_dsm.c that allows attackers to trigger heap buffer overflow via crafted track counts. Attackers can supply a DSM module whose numchn and numpat product wraps a 16-bit value, overwriting heap memory to cause crashes or potential code execution.

• CWE-190Integer Overflow or WraparoundThe 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.
