NVD Description

Note: Versions mentioned in the description apply only to the upstream fis-gtm package and not the fis-gtm package as distributed by Ubuntu. See How to fix? for Ubuntu:20.04 relevant fixed versions and status.

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.
