Release 2.4.5 (1 Nov 2022) -- compared to 2.4.4.2

  • oiiotool: new commands --iccread reads a named file and adds its contents
    as the ICCProfile metadata of the top image, --iccwrite saves the
    ICCProfile metadata of the top file to a named file. #3550
  • TIFF, JPEG, JPEG-2000, PNG, and PSD files containing ICC profiles now
    extract and report extra metadata related to aspects of those profiles.
    #3554
  • Python: support int8[] metadata and retrieving the ICCPorofile metadata.
    #3556
  • oiiotool: New expression syntax for retrieving metadata {TOP[foo]} is
    similar to the existing {TOP.foo}, if there is no foo metadata found,
    the former evaluates to an empty string, whereas the latter is an error.
    #3619
  • Strutil: new utf16_to_utf8(const std::u16string&) and
    Strutil::utf8_to_utf16wstring(). #3553
  • ustring: make std::hash work for ustring, add operator< for ustringhash,
    add from_hash() to ustringhash, make ustringhash == and != be
    constexpr for C++17 and beyond. #3577 Custom fmt formatter for ustringhash
    that prints the string rather than the hash. #3614
  • Build: the version number is now a CMake cache variable that can be
    overridden (caveat emptor). #3549
  • Build/security: New CMake cache variable FORTIFY_SOURCE, if enabled,
    builds with the specified gcc _FORTIFY_SOURCE option defined. This may be
    desirable for people deploying OIIO in security-sensitive environments.
    #3575
  • CI: testing now includes using undefined behavior sanitizer. #3565
  • Windows: protect against OpenEXR thread deadlock on shutdown. #3582
  • Windows: Work around a static destruction order issue. #3591
  • Windows: define NOGDI to keep the inclusion of windows.h from adding as
    many unneeded symbols. #3596
  • MinGW: fix incorrect symbol visibility issue for ImageBuf iterators. #3578
  • ARM: improve SIMD operations for ARM NEON. #3599
  • Docs: New RELEASING.md documents our releasing procedures. #3564 #3580
  • Docs: Better Windows build instructions in INSTALL.md. #3602
  • Fix missing OIIO::getattribute support for limits:channels and
    limits:imagesize_MB. #3617
  • BMP: fix reading 16bpp images. #3592
  • BMP: protect against corrupt pixel coordinates. (TALOS-2022-1630,
    CVE-2022-38143) #3620
  • DDS: fix alpha/luminance files, better testing. #3581
  • DDS: optimize loading of compressed images, improves 3-5x. #3583 #3584
  • DDS: Fix crashes for cubemap files when a cube face was not present, and
    check for invalid bits per pixel. (TALOS-2022-1634, CVE-2022-41838)
    (TALOS-2022-1635, CVE-2022-41999) #3625
  • HDR: fix a 8x (!) read performance regression for HDR files that was
    introduced in OIIO in 2.4. #3588 On top of that, speed up by another 4x
    beyond what we ever did before by speeding up the RGBE->float conversion.
    #3590
  • PNG: fix memory leaks when errors take an early exit. #3543 #3544
  • PSD: fix a PSD read error on ARM architecture. #3589
  • PSD: protect against corrupted embedded thumbnails. (TALOS-2022-1626,
    CVE-2022-41794) #3629
  • RAW: additional color metadata is now recognized: pre_mul, cam_mul,
    cam_xyz, rgb_cam. #3561 #3569 #3572
  • RLA: fix potential buffer overrun. (TALOS-2022-1629, CVE-2022-36354) #3624
  • Targa: string overflow safety. (TALOS-2022-1628, CVE-2022-4198) #3622
  • TIFF/JPEG/PSD: Fix EXIF bugs where corrupted exif blocks could overrun
    memory. (TALOS-2022-1626, CVE-2022-41794) (TALOS-2022-1632, CVE-2022-41684)
    #3627
  • TIFF: guard against corrupt files with buffer overflows. (TALOS-2022-1627,
    CVE-2022-41977) #3628
  • TIFF: guard against buffer overflow for certain CMYK files.
    (TALOS-2022-1633, CVE-2022-41639) (TALOS-2022-1643, CVE-2022-41988) #3632
