An issue was discovered in FIS GT.M through V7.0-000 (related to the YottaDB code base). Using crafted input, attackers can cause an integer underflow of the size of calls to memset in op_fnj3 in sr_port/op_fnj3.c in order to cause a segmentation fault and crash the application.
The product subtracts one value from another, such that the result is less than the minimum allowable integer value, which produces a value that is not equal to the correct result.
