Integer overflow in the ISO9660 writer in libarchive before 3.2.1 allows remote attackers to cause a denial of service (application crash) or execute arbitrary code via vectors related to verifying filename lengths when writing an ISO9660 archive, which trigger a buffer overflow.
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.
