An issue was discovered in the image crate before 0.21.3 for Rust, affecting the HDR image format decoder. Vec::set_len is called on an uninitialized vector, leading to a use-after-free and arbitrary code execution.
The product reuses or references memory after it has been freed. At some point afterward, the memory may be allocated again and saved in another pointer, while the original pointer references a location somewhere within the new allocation. Any operations using the original pointer are no longer valid because the memory “belongs” to the code that operates on the new pointer.
