Summary

Excelize is a Go language library for reading and writing Microsoft Excel spreadsheets. From 2.3.1 to 2.11.0, agile decryption accepts an attacker-controlled spinCount and performs that many password-key derivation iterations before verifier validation. OpenFile reaches agileDecrypt, which passes the unbounded spinCount to convertPasswdToKey before password verification. When a crafted OLE encrypted-workbook header supplies an excessive spinCount and the file is opened, the key-derivation loop performs unbounded attacker-selected work and cannot be cancelled, allowing an attacker to consume a CPU core for an attacker-controlled duration. No fixed version is available as of this review.
