Fixed a signed integer overflow in the `tj3CompressFromYUV8()`, +`tj3DecodeYUV8()`, `tj3DecompressToYUV8()`, and `tj3EncodeYUV8()` functions, +detected by the Clang and GCC undefined behavior sanitizers, that could be +triggered by setting the `align` parameter to an unreasonably large value. +This issue did not pose a security threat, but removing the warning made it +easier to detect actual security issues, should they arise in the future. + +2. Introduced a new parameter (`TJPARAM_MAXMEMORY` in the TurboJPEG C API and +`TJ.PARAM_MAXMEMORY` in the TurboJPEG Java API) and a corresponding TJBench +option (`-maxmemory`) for specifying the maximum amount of memory (in +megabytes) that will be allocated for intermediate buffers, which are used with +progressive JPEG compression and decompression, optimized baseline entropy +coding, lossless JPEG compression, and lossless transformation. The new +parameter and option serve the same purpose as the `max_memory_to_use` field in +the `jpeg_memory_mgr` struct in the libjpeg API, the `JPEGMEM` environment +variable, and the cjpeg/djpeg/jpegtran `-maxmemory` option. + +3. Introduced a new parameter (`TJPARAM_MAXPIXELS` in the TurboJPEG C API and +`TJ.PARAM_MAXPIXELS` in the TurboJPEG Java API) and a corresponding TJBench +option (`-maxpixels`) for specifying the maximum number of pixels that the +decompression, lossless transformation, and packed-pixel image loading +functions/methods will process. + +4. Fixed an error ("Unsupported color conversion request") that occurred when +attempting to decompress a 3-component lossless JPEG image without an Adobe +APP14 marker. The decompressor now assumes that a 3-component lossless JPEG +image without an Adobe APP14 marker uses the RGB colorspace if its component +IDs are 1, 2, and 3. + + 3.0.1 ===== @@ -2146,7 +2181,7 @@ and unit tests now work on those architectures. 0.0.93 ====== -### Significant changes since 0.0.91: +### Significant changes relative to 0.0.91: 1. 2982659: Fixed x86-64 build on FreeBSD systems |
