An issue was discovered in FIS GT.M through V7.0-000 (related to the YottaDB code base). A lack of parameter validation in calls to memcpy in str_tok in sr_unix/ztimeoutroutines.c allows attackers to attempt to read from a NULL 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.
