Summary
Ghidra through 12.2 contains an uncontrolled memory allocation vulnerability in BinaryField.read() that allows attackers to exhaust heap memory via an unchecked 32-bit length field. Attackers can persuade users to import a crafted GZF packed database file, triggering an OutOfMemoryError in PackedDatabase.open() that aborts the import and denies service.

Fencer Intel keeps one entry per vulnerability: the CVE id wins, then GHSA, and records that alias each other are merged, except that two CVEs always keep separate entries. The same data is available as JSON.
CPEs and fixed versions use Anchore's correction of NVD's data: Added CPE configurations because not yet analyzed by NVD.
