Summary
The eBook-speaker software, up to version 6.2.0, has a stack-based buffer overflow that a local attacker can trigger by crafting an EPUB or DAISY book with an overlong element name attribute, which crashes the reader when the user opens the file. The attacker must get the user to open that file, and the flaw enables denial of service rather than code execution or data theft.
