Integer overflow in Trihedral Engineering VTScada (formerly VTS) 6.5 through 9.x before 9.1.20, 10.x before 10.2.22, and 11.x before 11.1.07 allows remote attackers to cause a denial of service (server crash) via a crafted request, which triggers a large memory allocation.
Solution:
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.
Weaknesses in this category are related to improper calculation or conversion of numbers.
