CVE-2021-44504 Information

Description

An issue was discovered in FIS GT.M through V7.0-000 (related to the YottaDB code base). Using crafted input an attacker can cause a size variable stored as an signed int to equal an extremely large value which is interpreted as a negative value during a check. This value is then used in a memcpy call on the stack causing a memory segmentation fault.
