Title
OpenImageIO: TIFF 1-bit CMYK bit conversion heap out-of-bounds write
Summary
OpenImageIO is a toolset for reading, writing, and manipulating image files of any image file format relevant to VFX / animation. Prior to 3.1.16.0, A crafted 1-bit contiguous cmyk tiff is exposed through a native uint1 imagespec, so callers allocate a bit-packed buffer. tiffinput::read_native_scanline_locked() nevertheless invokes tiffinput::bit_convert() with 8-bit output and writes one expanded byte per value into that smaller buffer, resulting in a heap out-of-bounds write and memory corruption. The affected implementation is identified by src/tiff.imageio/tiffinput.cpp, TIFFInput::bit_convert(), TIFFInput::read_native_scanline_locked(), PHOTOMETRIC_SEPARATED, 1-bit CMYK, and native uint1 ImageSpec, which define the relevant source path, functions, state, and trigger. This issue is fixed in 3.1.16.0.

Title
OpenImageIO: TIFF multithreaded scanline read use-after-scope in `TIFFInput::read_native_scanlines`
Summary
OpenImageIO is a toolset for reading, writing, and manipulating image files of any image file format relevant to VFX / animation. Prior to 3.1.16.0, a crafted ZIP-compressed TIFF processed with TIFF multithreading enabled can make TIFFInput::read_native_scanlines() return through an error path while asynchronous strip-decompression work remains queued. Because task_set is declared before ok and compressed_scratch, those captured objects are destroyed before the task-set destructor waits, allowing worker tasks to use stale stack and heap storage, resulting in a use-after-scope crash and denial of service. The affected implementation is identified by src/tiff.imageio/tiffinput.cpp, TIFFInput::read_native_scanlines(), task_set, ok, compressed_scratch, and uncompress_one_strip(), which define the relevant source path, functions, state, and trigger. This issue is fixed in 3.1.16.0.

OpenImageIO: TGA-to-GIF palette split signed overflow causes SIGSEGV
Summary
OpenImageIO is a toolset for reading, writing, and manipulating image files of any image file format relevant to VFX / animation. Prior to 3.0.21.0, 3.1.16.0, and 3.2.0.3-beta1, A truncated tga can leave a pending gif frame that is processed during output close. gifsplitpalette() computes numpixels multiplied by the palette partition width in signed 32-bit arithmetic; a large image overflows that intermediate, corrupts subpixelsa, and drives an out-of-bounds read while building the gif palette, resulting in a process crash and denial of service. The affected implementation is identified by src/gif.imageio/gif.h, GifSplitPalette(), numPixels, subPixelsA, GIFOutput, and truncated TGA input, which define the relevant source path, functions, state, and trigger. This issue is fixed in versions 3.0.21.0, 3.1.16.0, and 3.2.0.3-beta1.

Title
OpenImageIO: Cineon invalid bit depth heap out-of-bounds write
Summary
OpenImageIO is a toolset for reading, writing, and manipulating image files of any image file format relevant to VFX / animation. Prior to 3.0.21.0, 3.1.16.0, and 3.2.0.3-beta1, A crafted cineon image can declare unsupported component bit depth 26. cineoninput::open() maps it to a 32-bit imagespec, but libcineon maps the unsupported depth to an 8-byte value, so cineoninput::read_native_scanline() causes attacker-controlled data to be written beyond the 4-byte-per-pixel caller buffer, resulting in a heap out-of-bounds write and memory corruption. The affected implementation is identified by src/cineon.imageio/cineoninput.cpp, CineonInput::open(), CineonInput::read_native_scanline(), ComponentDataSize(), bit depth 26, and ImageSpec, which define the relevant source path, functions, state, and trigger. This issue is fixed in versions 3.0.21.0, 3.1.16.0, and 3.2.0.3-beta1.

Title
OpenImageIO: PSD RawColor invalid color mode causes global out-of-bounds read and allocation DoS
Summary
OpenImageIO is a toolset for reading, writing, and manipulating image files of any image file format relevant to VFX / animation. Prior to 3.0.21.0, 3.1.16.0, and 3.2.0.3-beta1, A crafted psd with an invalid color_mode bypasses normal validation when oiio:rawcolor or psd:rawdata is enabled. psdinput::setup() then uses the attacker-controlled value to index fixed color-mode tables, causing a global out-of-bounds read and potentially a bogus allocation, resulting in denial of service. The affected implementation is identified by src/psd.imageio/psdinput.cpp, PSDInput::validate_header(), PSDInput::setup(), oiio:RawColor, psd:RawData, color_mode, and mode_channel_count, which define the relevant source path, functions, state, and trigger. This issue is fixed in versions 3.0.21.0, 3.1.16.0, and 3.2.0.3-beta1.

Title
OpenImageIO OpenEXR plugin partial edge tile heap out-of-bounds write
Summary
OpenImageIO is a toolset for reading, writing, and manipulating image files of any image file format relevant to VFX / animation. Prior to 3.0.21.0, 3.1.16.0, and 3.2.0.3-beta1, A valid tiled openexr image whose width is not a multiple of its tile width can trigger an overflow when a caller reads a partial edge-tile rectangle. openexrinput::read_native_tiles() copies each row into the caller buffer using the padded whole-tile scanline_stride rather than user_scanline_bytes for the requested rectangle, resulting in a heap out-of-bounds write and memory corruption. The affected implementation is identified by src/openexr.imageio/exrinput.cpp, OpenEXRInput::read_native_tiles(), partial edge tile, user_scanline_bytes, and scanline_stride, which define the relevant source path, functions, state, and trigger. This issue is fixed in versions 3.0.21.0, 3.1.16.0, and 3.2.0.3-beta1.

Title
OpenImageIO: PSD RawColor indexed image out-of-bounds read in `interleave_row`
Summary
OpenImageIO is a toolset for reading, writing, and manipulating image files of any image file format relevant to VFX / animation. Prior to 3.0.21.0, 3.1.16.0, and 3.2.0.3-beta1, An indexed psd with transparency metadata creates fewer stored channel_buffers than the spec.nchannels value advertised by the rawcolor path. when oiio:rawcolor or psd:rawdata is enabled, psdinput::read_native_scanline() passes spec.nchannels to psdinput::interleave_row(), which indexes beyond channel_buffers, resulting in a heap out-of-bounds read and process crash. The affected implementation is identified by src/psd.imageio/psdinput.cpp, PSDInput::read_native_scanline(), PSDInput::interleave_row(), oiio:RawColor, psd:RawData, channel_buffers, and spec.nchannels, which define the relevant source path, functions, state, and trigger. This issue is fixed in versions 3.0.21.0, 3.1.16.0, and 3.2.0.3-beta1.

Title
OpenImageIO: IFF ZBUFFER tile read writes past caller tile buffer
Summary
OpenImageIO is a toolset for reading, writing, and manipulating image files of any image file format relevant to VFX / animation. Prior to 3.0.21.0, 3.1.16.0, and 3.2.0.3-beta1, A zbuffer-only tiled iff is exposed with a 16-bit public imagespec while the decoder retains a 32-bit internal pixel size. iffinput::read_native_tile() copies according to m_header.pixel_bytes() rather than imagespec::tile_bytes(true), and a failed read can leave m_buf nonempty so a later call copies partially initialized data into the undersized caller buffer, resulting in a heap out-of-bounds write and memory corruption. The affected implementation is identified by src/iff.imageio/iffinput.cpp, IffInput::read_native_tile(), ImageSpec::tile_bytes(true), m_header.pixel_bytes(), ZBUFFER, and m_buf, which define the relevant source path, functions, state, and trigger. This issue is fixed in versions 3.0.21.0, 3.1.16.0, and 3.2.0.3-beta1.

OpenImageIO: Heap-buffer-overread in IffInput::readimg() when ZBUFFER flag is set
Summary
OpenImageIO is a toolset for reading, writing, and manipulating image files of any image file format relevant to VFX / animation. Prior to 3.0.20.0, 3.1.15.0, and 3.2.0.3-beta1, An uncompressed 16-bit iff image with a z-buffer makes iffinput::readimg() allocate a temporary scanline from m_header.rgba_count but copy from it using m_header.pixel_bytes(), whose stride also includes z-buffer bytes. the oversized memcpy reads beyond the temporary heap buffer and copies adjacent memory into the output image, resulting in a crash or disclosure of adjacent heap data. The affected implementation is identified by src/iff.imageio/iffinput.cpp, IffInput::readimg(), m_header.rgba_count, and m_header.pixel_bytes(), which define the relevant source path, functions, state, and trigger. This issue is fixed in versions 3.0.20.0, 3.1.15.0, and 3.2.0.3-beta1.

Title
OpenImageIO: Stack buffer overflow in OpenImageIO Cineon reader via unchecked numberOfElements
Summary
OpenImageIO is a toolset for reading, writing, and manipulating image files of any image file format relevant to VFX / animation. Prior to 3.0.20.0, 3.1.15.0, and 3.2.0.3-beta1, A crafted cineon file can supply a numberofelements value greater than the format maximum of eight. cineoninput::open() uses that unchecked value as the loop bound while filling the fixed strings[8] array, writing pointers beyond the stack buffer and into adjacent state, resulting in memory corruption and denial of service. The affected implementation is identified by src/cineon.imageio/cineoninput.cpp, CineonInput::open(), numberOfElements, and strings[8], which define the relevant source path, functions, state, and trigger. This issue is fixed in versions 3.0.20.0, 3.1.15.0, and 3.2.0.3-beta1.

Prior to 3.0.20.0, 3.1.15.0, and 3.2.0.3-beta1, A crafted fits stream containing consecutive 2880-byte header blocks without the mandatory end keyword makes fitsinput::read_fits_header() call itself without a depth bound. repeated recursive parsing exhausts the application stack, resulting in denial of service. The affected implementation is identified by src/fits.imageio/fitsinput.cpp, FitsInput::read_fits_header(), END keyword, and 2880-byte FITS header blocks, which define the relevant source path, functions, state, and trigger. This issue is fixed in versions 3.0.20.0, 3.1.15.0, and 3.2.0.3-beta1.

Title
OpenImageIO: Segmentation Fault in BmpInput::read_native_scanline (bmpinput.cpp:399)
Summary
OpenImageIO is a toolset for reading, writing, and manipulating image files of any image file format relevant to VFX / animation. Prior to versions 3.0.16.0 and 3.1.11.0, processing a crafted BMP file through oiiotool or an application linked to OpenImageIO can reach BMP palette handling in src/bmp.imageio/bmpinput.cpp with an empty color table. BmpInput::read_native_scanline then performs an invalid palette read while decoding an RLE-compressed scanline, causing a process crash and denial of service. This issue is fixed in versions 3.0.16.0 and 3.1.11.0.

Title
OpenImageIO: Integer wraparound in bounds check of decode_pixel leads to out-of-bounds read in TGA paletted image decoder
Summary
OpenImageIO is a toolset for reading, writing, and manipulating image files of any image file format relevant to VFX / animation. Prior to 3.0.18.0 and 3.1.13.0, the bounds check in TGAInput::decode_pixel computes k + palbytespp as unsigned 32-bit arithmetic. When k = 0xFFFFFFFC and palbytespp = 4, the addition wraps to 0, which compares less than palette_alloc_size and passes the check. The subsequent palette access uses the unwrapped k (0xFFFFFFFC) as the index, reading ~4 GB past the start of the palette buffer — SEGV. This vulnerability is fixed in 3.0.18.0 and 3.1.13.0.

Title
OpenImageIO: Signed integer overflow in SwapRGBABytes loop index leads to out-of-bounds read/write in DPX ABGR decoder
Summary
OpenImageIO is a toolset for reading, writing, and manipulating image files of any image file format relevant to VFX / animation. Prior to 3.0.18.0 and 3.1.13.0, a signed 32-bit integer overflow in the loop index expression i * 4 inside SwapRGBABytes() causes the function to compute a large negative pointer offset when processing kABGR DPX images with large dimensions. The immediate crash is an out-of-bounds read (the memcpy at line 45 reads from &input[i * 4] first), but the subsequent write operations at lines 46–49 target the same wrapped offset — making this a combined OOB read+write primitive. This vulnerability is fixed in 3.0.18.0 and 3.1.13.0.

OpenImageIO: Signed integer overflow in ConvertCbYCrYToRGB leads to heap out-of-bounds write in DPX 4:2:2 decoder
Summary
OpenImageIO is a toolset for reading, writing, and manipulating image files of any image file format relevant to VFX / animation. Prior to 3.0.18.0 and 3.1.13.0, a signed 32-bit integer overflow in the pixel-loop index expression i * 3 inside ConvertCbYCrYToRGB() causes the function to compute a large negative pointer offset into the output buffer, producing an out-of-bounds write that crashes the process. This vulnerability is fixed in 3.0.18.0 and 3.1.13.0.

Title
OpenImageIO: Integer overflow in QueryRGBBufferSizeInternal leads to heap out-of-bounds write in DPX decoder (kCbYCr and kABGR)
Summary
OpenImageIO is a toolset for reading, writing, and manipulating image files of any image file format relevant to VFX / animation. Prior to 3.0.18.0 and 3.1.13.0, a signed integer overflow in QueryRGBBufferSizeInternal() in DPXColorConverter.cpp leads to a heap-based out-of-bounds write when processing crafted DPX image files. The function computes buffer sizes using 32-bit signed integer arithmetic with negative multipliers (e.g., pixels * -3 * bytes for kCbYCr descriptors and pixels * -4 * bytes for kABGR descriptors), where a negative result is used as an in-band signal that no separate buffer is needed. When the pixel count is sufficiently large, the multiplication overflows INT_MIN and wraps to a small positive value. The caller in dpxinput.cpp interprets this positive value as a required buffer size, allocates an undersized heap buffer via m_decodebuf.resize(), and then writes the full image data into it via fread, resulting in a heap buffer overflow. An attacker can exploit this by crafting a DPX file that triggers the overflow, causing a denial of service (crash) or potentially arbitrary code execution through heap corruption in any application that reads pixel data using OpenImageIO. This vulnerability is fixed in 3.0.18.0 and 3.1.13.0.

OpenImageIO: JPEG2000 (OpenJPH) signed integer overflow in buffer allocation
Summary
OpenImageIO is a toolset for reading, writing, and manipulating image files of any image file format relevant to VFX / animation. Prior to 3.0.18.0 and 3.1.13.0, jpeg2000input.cpp:395 computes buffer size as const int bufsize = w * h * ch * buffer_bpp using signed 32-bit arithmetic. When the product exceeds INT_MAX, the result wraps to 0 or a small value. m_buf.resize() allocates an undersized buffer, and subsequent pixel write loops cause heap overflow. Conditional on USE_OPENJPH build flag. This vulnerability is fixed in 3.0.18.0 and 3.1.13.0.

Title
OpenImageIO: TGA-to-GIF palette split signed overflow causes SIGSEGV
Summary
OpenImageIO is a toolset for reading, writing, and manipulating image files of any image file format relevant to VFX / animation. Prior to 3.0.21.0, 3.1.16.0, and 3.2.0.3-beta1, A truncated tga can leave a pending gif frame that is processed during output close. gifsplitpalette() computes numpixels multiplied by the palette partition width in signed 32-bit arithmetic; a large image overflows that intermediate, corrupts subpixelsa, and drives an out-of-bounds read while building the gif palette, resulting in a process crash and denial of service. The affected implementation is identified by src/gif.imageio/gif.h, GifSplitPalette(), numPixels, subPixelsA, GIFOutput, and truncated TGA input, which define the relevant source path, functions, state, and trigger. This issue is fixed in versions 3.0.21.0, 3.1.16.0, and 3.2.0.3-beta1.

Title
OpenImageIO: TIFF 1-bit CMYK bit conversion heap out-of-bounds write
Summary
OpenImageIO is a toolset for reading, writing, and manipulating image files of any image file format relevant to VFX / animation. Prior to 3.1.16.0, A crafted 1-bit contiguous cmyk tiff is exposed through a native uint1 imagespec, so callers allocate a bit-packed buffer. tiffinput::read_native_scanline_locked() nevertheless invokes tiffinput::bit_convert() with 8-bit output and writes one expanded byte per value into that smaller buffer, resulting in a heap out-of-bounds write and memory corruption. The affected implementation is identified by src/tiff.imageio/tiffinput.cpp, TIFFInput::bit_convert(), TIFFInput::read_native_scanline_locked(), PHOTOMETRIC_SEPARATED, 1-bit CMYK, and native uint1 ImageSpec, which define the relevant source path, functions, state, and trigger. This issue is fixed in 3.1.16.0.

Title
OpenImageIO: Cineon invalid bit depth heap out-of-bounds write
Summary
OpenImageIO is a toolset for reading, writing, and manipulating image files of any image file format relevant to VFX / animation. Prior to 3.0.21.0, 3.1.16.0, and 3.2.0.3-beta1, A crafted cineon image can declare unsupported component bit depth 26. cineoninput::open() maps it to a 32-bit imagespec, but libcineon maps the unsupported depth to an 8-byte value, so cineoninput::read_native_scanline() causes attacker-controlled data to be written beyond the 4-byte-per-pixel caller buffer, resulting in a heap out-of-bounds write and memory corruption. The affected implementation is identified by src/cineon.imageio/cineoninput.cpp, CineonInput::open(), CineonInput::read_native_scanline(), ComponentDataSize(), bit depth 26, and ImageSpec, which define the relevant source path, functions, state, and trigger. This issue is fixed in versions 3.0.21.0, 3.1.16.0, and 3.2.0.3-beta1.

Title
OpenImageIO: IFF ZBUFFER tile read writes past caller tile buffer
Summary
OpenImageIO is a toolset for reading, writing, and manipulating image files of any image file format relevant to VFX / animation. Prior to 3.0.21.0, 3.1.16.0, and 3.2.0.3-beta1, A zbuffer-only tiled iff is exposed with a 16-bit public imagespec while the decoder retains a 32-bit internal pixel size. iffinput::read_native_tile() copies according to m_header.pixel_bytes() rather than imagespec::tile_bytes(true), and a failed read can leave m_buf nonempty so a later call copies partially initialized data into the undersized caller buffer, resulting in a heap out-of-bounds write and memory corruption. The affected implementation is identified by src/iff.imageio/iffinput.cpp, IffInput::read_native_tile(), ImageSpec::tile_bytes(true), m_header.pixel_bytes(), ZBUFFER, and m_buf, which define the relevant source path, functions, state, and trigger. This issue is fixed in versions 3.0.21.0, 3.1.16.0, and 3.2.0.3-beta1.

Title
OpenImageIO: TIFF multithreaded scanline read use-after-scope in `TIFFInput::read_native_scanlines`
Summary
OpenImageIO is a toolset for reading, writing, and manipulating image files of any image file format relevant to VFX / animation. Prior to 3.1.16.0, a crafted ZIP-compressed TIFF processed with TIFF multithreading enabled can make TIFFInput::read_native_scanlines() return through an error path while asynchronous strip-decompression work remains queued. Because task_set is declared before ok and compressed_scratch, those captured objects are destroyed before the task-set destructor waits, allowing worker tasks to use stale stack and heap storage, resulting in a use-after-scope crash and denial of service. The affected implementation is identified by src/tiff.imageio/tiffinput.cpp, TIFFInput::read_native_scanlines(), task_set, ok, compressed_scratch, and uncompress_one_strip(), which define the relevant source path, functions, state, and trigger. This issue is fixed in 3.1.16.0.

Title
OpenImageIO: PSD RawColor invalid color mode causes global out-of-bounds read and allocation DoS
Summary
OpenImageIO is a toolset for reading, writing, and manipulating image files of any image file format relevant to VFX / animation. Prior to 3.0.21.0, 3.1.16.0, and 3.2.0.3-beta1, A crafted psd with an invalid color_mode bypasses normal validation when oiio:rawcolor or psd:rawdata is enabled. psdinput::setup() then uses the attacker-controlled value to index fixed color-mode tables, causing a global out-of-bounds read and potentially a bogus allocation, resulting in denial of service. The affected implementation is identified by src/psd.imageio/psdinput.cpp, PSDInput::validate_header(), PSDInput::setup(), oiio:RawColor, psd:RawData, color_mode, and mode_channel_count, which define the relevant source path, functions, state, and trigger. This issue is fixed in versions 3.0.21.0, 3.1.16.0, and 3.2.0.3-beta1.

Title
OpenImageIO OpenEXR plugin partial edge tile heap out-of-bounds write
Summary
OpenImageIO is a toolset for reading, writing, and manipulating image files of any image file format relevant to VFX / animation. Prior to 3.0.21.0, 3.1.16.0, and 3.2.0.3-beta1, A valid tiled openexr image whose width is not a multiple of its tile width can trigger an overflow when a caller reads a partial edge-tile rectangle. openexrinput::read_native_tiles() copies each row into the caller buffer using the padded whole-tile scanline_stride rather than user_scanline_bytes for the requested rectangle, resulting in a heap out-of-bounds write and memory corruption. The affected implementation is identified by src/openexr.imageio/exrinput.cpp, OpenEXRInput::read_native_tiles(), partial edge tile, user_scanline_bytes, and scanline_stride, which define the relevant source path, functions, state, and trigger. This issue is fixed in versions 3.0.21.0, 3.1.16.0, and 3.2.0.3-beta1.

Title
OpenImageIO: PSD RawColor indexed image out-of-bounds read in `interleave_row`
Summary
OpenImageIO is a toolset for reading, writing, and manipulating image files of any image file format relevant to VFX / animation. Prior to 3.0.21.0, 3.1.16.0, and 3.2.0.3-beta1, An indexed psd with transparency metadata creates fewer stored channel_buffers than the spec.nchannels value advertised by the rawcolor path. when oiio:rawcolor or psd:rawdata is enabled, psdinput::read_native_scanline() passes spec.nchannels to psdinput::interleave_row(), which indexes beyond channel_buffers, resulting in a heap out-of-bounds read and process crash. The affected implementation is identified by src/psd.imageio/psdinput.cpp, PSDInput::read_native_scanline(), PSDInput::interleave_row(), oiio:RawColor, psd:RawData, channel_buffers, and spec.nchannels, which define the relevant source path, functions, state, and trigger. This issue is fixed in versions 3.0.21.0, 3.1.16.0, and 3.2.0.3-beta1.

Title
OpenImageIO: Stack buffer overflow in OpenImageIO Cineon reader via unchecked numberOfElements
Summary
OpenImageIO is a toolset for reading, writing, and manipulating image files of any image file format relevant to VFX / animation. Prior to 3.0.20.0, 3.1.15.0, and 3.2.0.3-beta1, A crafted cineon file can supply a numberofelements value greater than the format maximum of eight. cineoninput::open() uses that unchecked value as the loop bound while filling the fixed strings[8] array, writing pointers beyond the stack buffer and into adjacent state, resulting in memory corruption and denial of service. The affected implementation is identified by src/cineon.imageio/cineoninput.cpp, CineonInput::open(), numberOfElements, and strings[8], which define the relevant source path, functions, state, and trigger. This issue is fixed in versions 3.0.20.0, 3.1.15.0, and 3.2.0.3-beta1.

Title
OpenImageIO: Unbounded recursion in FITS header parser leads to stack overflow
Summary
OpenImageIO is a toolset for reading, writing, and manipulating image files of any image file format relevant to VFX / animation. Prior to 3.0.20.0, 3.1.15.0, and 3.2.0.3-beta1, A crafted fits stream containing consecutive 2880-byte header blocks without the mandatory end keyword makes fitsinput::read_fits_header() call itself without a depth bound. repeated recursive parsing exhausts the application stack, resulting in denial of service. The affected implementation is identified by src/fits.imageio/fitsinput.cpp, FitsInput::read_fits_header(), END keyword, and 2880-byte FITS header blocks, which define the relevant source path, functions, state, and trigger. This issue is fixed in versions 3.0.20.0, 3.1.15.0, and 3.2.0.3-beta1.

Title
OpenImageIO: Heap-buffer-overread in IffInput::readimg() when ZBUFFER flag is set
Summary
OpenImageIO is a toolset for reading, writing, and manipulating image files of any image file format relevant to VFX / animation. Prior to 3.0.20.0, 3.1.15.0, and 3.2.0.3-beta1, An uncompressed 16-bit iff image with a z-buffer makes iffinput::readimg() allocate a temporary scanline from m_header.rgba_count but copy from it using m_header.pixel_bytes(), whose stride also includes z-buffer bytes. the oversized memcpy reads beyond the temporary heap buffer and copies adjacent memory into the output image, resulting in a crash or disclosure of adjacent heap data. The affected implementation is identified by src/iff.imageio/iffinput.cpp, IffInput::readimg(), m_header.rgba_count, and m_header.pixel_bytes(), which define the relevant source path, functions, state, and trigger. This issue is fixed in versions 3.0.20.0, 3.1.15.0, and 3.2.0.3-beta1.

Prior to 3.0.20.0, 3.1.15.0, and 3.2.0.3-beta1, An uncompressed 16-bit iff image with a z-buffer makes iffinput::readimg() allocate a temporary scanline from m_header.rgba_count but copy from it using m_header.pixel_bytes(), whose stride also includes z-buffer bytes. the oversized memcpy reads beyond the temporary heap buffer and copies adjacent memory into the output image, resulting in a crash or disclosure of adjacent heap data.

Title
OpenImageIO: Segmentation Fault in BmpInput::read_native_scanline (bmpinput.cpp:399)
Summary
OpenImageIO is a toolset for reading, writing, and manipulating image files of any image file format relevant to VFX / animation. Prior to versions 3.0.16.0 and 3.1.11.0, processing a crafted BMP file through oiiotool or an application linked to OpenImageIO can reach BMP palette handling in src/bmp.imageio/bmpinput.cpp with an empty color table. BmpInput::read_native_scanline then performs an invalid palette read while decoding an RLE-compressed scanline, causing a process crash and denial of service. This issue is fixed in versions 3.0.16.0 and 3.1.11.0.
Severity
