Technical details

An unrestricted upload vulnerability (CWE-434) exists in Apache Answer through version 2.0.0. The application fails to properly validate or restrict the processing of certain image formats during decoding. An authenticated attacker can upload a maliciously crafted TIFF image that triggers excessive memory allocation during the decoding process, leading to an Out-of-Memory (OOM) condition and a crash of the server process. The fix, introduced in version 2.0.1, involves enhancing image decoding by implementing format-specific checks for safer types like JPEG, PNG, and GIF.
