CVE-2021-44499: Fisglobal Gt.m

High severity, CVSS 7.5. EPSS: 1.7% chance of exploitation in the next 30 days.

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 call to $Extract to force an signed integer holding the size of a buffer to take on a large negative number, which is then used as the length of a memcpy call that occurs on the stack, causing a buffer overflow.
