An issue was discovered in FIS GT.M through V7.0-000 (related to the YottaDB code base). A lack of input validation in calls to do_verify in sr_unix/do_verify.c allows attackers to attempt to jump to a NULL pointer by corrupting a function pointer.
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.
