CVE-2021-44493: n/a vulnerability

CVE-2021-44493: An issue was discovered in YottaDB through r1.32 and V7.0-000 and FIS GT.M through V7.0-000.

An issue was discovered in YottaDB through r1.32 and V7.0-000 and FIS GT.M through V7.0-000. 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.

Security readout for executives and security teams

YottaDB and FIS GT.M versions named in the CVE can mishandle crafted input to $Extract, turning a buffer size into a negative value and causing a stack buffer overflow. Business urgency depends on whether these database runtimes are deployed and reachable by untrusted input. Exposure is limited to environments running YottaDB through r1.32 or V7.0-000, or FIS GT.M through V7.0-000, especially where application logic accepts untrusted input that reaches $Extract. Treat as an exposure-confirmation item first. Prioritize remediation if these runtimes support production systems or process external input, because stack overflows in database runtimes can create stability and security risk. Mitigation focus: Inventory all YottaDB and FIS GT.M deployments and versions.; Review YottaDB issue 828 and GT.M release notes for vendor guidance.; Upgrade or patch according to vendor-supported fixed versions..
