An issue was discovered in FIS GT.M through V7.0-000 (related to the YottaDB code base). Using crafted input, attackers can cause a type to be incorrectly initialized in the function f_incr in sr_port/f_incr.c and cause a crash due to a NULL pointer dereference.
A NULL pointer dereference occurs when the application dereferences a pointer that it expects to be valid, but is NULL, typically causing a crash or exit.
