Sensitive memory disclosure via crafted file parsing
Published Aug 24, 2021 · Updated Apr 23, 2025
Out-of-bounds read in Adobe Animate 21.0.6 and earlier allows attackers to disclose sensitive memory via a specially crafted file. The parser reads beyond a valid buffer when processing malicious file data, exposing memory from the current user context. Exploitation requires a victim to open the file, and the documented impact is information disclosure without integrity or availability effects.
