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 bufferbpp using signed 32-bit arithmetic. When the product exceeds INTMAX, the result wraps to 0 or a small value. mbuf.resize() allocates an undersized buffer, and subsequent pixel write loops cause heap overflow. Conditional on USEOPENJPH build flag. This vulnerability is fixed in 3.0.18.0 and 3.1.13.0.
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::decodepixel computes k + palbytespp as unsigned 32-bit arithmetic. When k = 0xFFFFFFFC and palbytespp = 4, the addition wraps to 0, which compares less than paletteallocsize 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.

OpenImageIO v3.1.0.0dev was discovered to contain a segmentation violation via the component /OpenImageIO/stringview.h.
OpenImageIO v3.1.0.0dev was discovered to contain a heap overflow via the component OpenImageIOv310::farmhash::inlined::Fetch64(char const).
An allocation-size-too-big bug in the component /imagebuf.cpp of OpenImageIO v3.1.0.0dev may cause a Denial of Service (DoS) when the program to requests to allocate too much space.
OpenImageIO v3.1.0.0dev was discovered to contain a heap overflow via the component /OpenImageIO/fmath.h.
OpenImageIO is a toolset for reading, writing, and manipulating image files of any image file format relevant to VFX / animation via a format-agnostic API with a feature set, scalability, and robustness needed for feature film production. In affected versions there is a bug in the heif input functionality of OpenImageIO. Specifically, in HeifInput::seeksubimage(). In the worst case, this can lead to an information disclosure vulnerability, particularly for programs that directly use the ImageInput APIs. This bug has been addressed in commit 0a2dcb4c which is included in the 2.5.13.1 release. Users are advised to upgrade. There are no known workarounds for this issue.
Buffer Overflow vulnerability in OpenImageIO oiio v.2.4.12.0 allows a remote attacker to execute arbitrary code and cause a denial of service via the readsubimagedata function.
An issue in OpenImageIO oiio v.2.4.12.0 allows a remote attacker to execute arbitrary code and cause a denial of service via the readrleimage function of file bifs/unquantize.c
Buffer Overflow vulnerability in OpenImageIO v.2.4.12.0 and before allows a remote to execute arbitrary code and obtain sensitive information via a crafted file to the readimg function.
A vulnerability was found in OpenImageIO, where a heap buffer overflow exists in the src/gif.imageio/gifinput.cpp file. This flaw allows a remote attacker to pass a specially crafted file to the application, which triggers a heap-based buffer overflow and could cause a crash, leading to a denial of service.
An information disclosure vulnerability exists in the TGAInput::readtga2header functionality of OpenImageIO Project OpenImageIO v2.4.7.1. A specially crafted targa file can lead to a disclosure of sensitive information. An attacker can provide a malicious file to trigger this vulnerability.
A denial of service vulnerability exists in the FitsOutput::close() functionality of OpenImageIO Project OpenImageIO v2.4.7.1. A specially crafted ImageOutput Object can lead to denial of service. An attacker can provide malicious input to trigger this vulnerability.
An out-of-bounds read vulnerability exists in the TGAInput::decodepixel() functionality of OpenImageIO Project OpenImageIO v2.4.7.1. A specially crafted targa file can lead to information disclosure. An attacker can provide a malicious file to trigger this vulnerability.
Multiple memory corruption vulnerabilities exist in the IFFOutput alignment padding functionality of OpenImageIO Project OpenImageIO v2.4.4.2. A specially crafted ImageOutput Object can lead to arbitrary code execution. An attacker can provide malicious input to trigger these vulnerabilities.This vulnerability arises when the mspec.format is TypeDesc::UINT16.
A heap out-of-bounds read vulnerability exists in the RLA format parser of OpenImageIO master-branch-9aeece7a and v2.3.19.0. More specifically, in the way run-length encoded byte spans are handled. A malformed RLA file can lead to an out-of-bounds read of heap metadata which can result in sensitive information leak. An attacker can provide a malicious file to trigger this vulnerability.
A stack-based buffer overflow vulnerability exists in the TGA file format parser of OpenImageIO v2.3.19.0. A specially-crafted targa file can lead to out of bounds read and write on the process stack, which can lead to arbitrary code execution. An attacker can provide a malicious file to trigger this vulnerability.
An out-of-bounds write vulnerability exists in the OpenImageIO::addexifitemtospec functionality of OpenImageIO Project OpenImageIO v2.4.4.2. Specially-crafted exif metadata can lead to stack-based memory corruption. An attacker can provide a malicious file to trigger this vulnerability.
A heap out of bounds read vulnerability exists in the OpenImageIO master-branch-9aeece7a when parsing the image file directory part of a PSD image file. A specially-crafted .psd file can cause a read of arbitrary memory address which can lead to denial of service. An attacker can provide a malicious file to trigger this vulnerability.
A heap out of bounds read vulnerability exists in the handling of IPTC data while parsing TIFF images in OpenImageIO v2.3.19.0. A specially-crafted TIFF file can cause a read of adjacent heap memory, which can leak sensitive process information. An attacker can provide a malicious file to trigger this vulnerability.
A heap based buffer overflow vulnerability exists in the PSD thumbnail resource parsing code of OpenImageIO 2.3.19.0. A specially-crafted PSD file can lead to arbitrary code execution. An attacker can provide a malicious file to trigger this vulnerability.
A heap based buffer overflow vulnerability exists in tile decoding code of TIFF image parser in OpenImageIO master-branch-9aeece7a and v2.3.19.0. A specially-crafted TIFF file can lead to an out of bounds memory corruption, which can result in arbitrary code execution. An attacker can provide a malicious file to trigger this vulnerability.
A code execution vulnerability exists in the DDS scanline parsing functionality of OpenImageIO Project OpenImageIO v2.4.4.2. A specially-crafted .dds can lead to a heap buffer overflow. An attacker can provide a malicious file to trigger this vulnerability.
An out of bounds read vulnerability exists in the way OpenImageIO version v2.3.19.0 processes string fields in TIFF image files. A specially-crafted TIFF file can lead to information disclosure. An attacker can provide a malicious file to trigger this vulnerability.
