da2a27ef	2017-03-18T16:15:14	Honor max_memory_to_use/JPEGMEM/-maxmemory This re-introduces a feature of the obsolete system-specific libjpeg memory managers-- namely the ability to limit the amount of main memory used by the library during decompression or multi-pass compression. This is mainly beneficial for two reasons: - Works around a 2 GB limit in libFuzzer - Allows security-sensitive applications to set a memory limit for the JPEG decoder so as to work around the progressive JPEG exploit (LJT-01-004) described here: http://www.libjpeg-turbo.org/pmwiki/uploads/About/TwoIssueswiththeJPEGStandard.pdf This commit also removes obsolete documentation regarding the MS-DOS memory manager (which itself was removed long ago) and changes the documentation of the -maxmemory switch and JPEGMEM environment variable to reflect the fact that backing stores are never used in libjpeg-turbo. Inspired by: https://github.com/caolanm/libjpeg-turbo/commit/066fee2e7d6834f24838bc1896aa38ca77209e3c Closes #143
44b2399a	2017-01-19T15:18:57	libjpeg API: Support reading/writing ICC profiles This commit does the following: -- Merges the two glueware functions (read_icc_profile() and write_icc_profile()) from iccjpeg.c, which is contained in downstream projects such as LCMS, Ghostscript, Mozilla, etc. These functions were originally intended for inclusion in libjpeg, but Tom Lane left the IJG before that could be accomplished. Since then, programs and libraries that needed to embed/extract ICC profiles in JPEG files had to include their own local copy of iccjpeg.c, which is suboptimal. -- The new functions were prefixed with jpeg_ and split into separate files for the compressor and decompressor, per the existing libjpeg coding standards. -- jpeg_write_icc_profile() was made slightly more fault-tolerant. It will now trigger a libjpeg error if it is called before jpeg_start_compress() or if it is passed NULL arguments. -- jpeg_read_icc_profile() was made slightly more fault-tolerant. It will now trigger a libjpeg error if it is called before jpeg_read_header() or if it is passed NULL arguments. It will also now trigger libjpeg warnings if the ICC profile data is corrupt. -- The code comments have been wordsmithed. -- Note that the one-line setup_read_icc_profile() function was not included. Instead, libjpeg.txt now documents the need to call jpeg_save_markers(cinfo, JPEG_APP0 + 2, 0xFFFF) prior to calling jpeg_read_header(), if jpeg_read_icc_profile() is to be used. -- Adds documentation for the new functions to libjpeg.txt. -- Adds an -icc switch to cjpeg and jpegtran that allows those programs to embed an ICC profile in the JPEG files they generate. -- Adds an -icc switch to djpeg that allows that program to extract an ICC profile from a JPEG file while decompressing. -- Adds appropriate unit tests for all of the above. -- Bumps the SO_AGE of the libjpeg API library to indicate the presence of new API functions. Note that the licensing information was obtained from: https://github.com/mm2/Little-CMS/issues/37#issuecomment-66450180
