CVE-2023-5841 – OpenEXR Heap Overflow in Scanline Deep Data Parsing
https://notcve.org/view.php?id=CVE-2023-5841
Due to a failure in validating the number of scanline samples of a OpenEXR file containing deep scanline data, Academy Software Foundation OpenEX image parsing library version 3.2.1 and prior is susceptible to a heap-based buffer overflow vulnerability. This issue was resolved as of versions v3.2.2 and v3.1.12 of the affected library. Debido a un fallo en la validación del número de muestras de líneas de escaneo de un archivo OpenEXR que contiene datos de líneas de escaneo profundas, la librería de análisis de imágenes Academy Software Foundation OpenEX versión 3.2.1 y anteriores es susceptible a una vulnerabilidad de desbordamiento de búfer en la región Heap de la memoria. A vulnerability was found in the Academy Software Foundation OpenEXR and requires that a malicious EXR file image is parsed by the target device or environment using OpenEXR. This issue occurs due to a failure in validating the number of scanline samples of an OpenEXR file containing deep scanline data, allowing a read or write primitive based on the provided EXR file attributes. • https://lists.fedoraproject.org/archives/list/package-announce@lists.fedoraproject.org/message/LSB6DB5LAKGPLRXEF5HDNGUMT7GIFT2C https://lists.fedoraproject.org/archives/list/package-announce@lists.fedoraproject.org/message/XWMINVKQLSUHECXBSQMZFCSDRIHFOJJI https://takeonme.org/cves/CVE-2023-5841.html https://access.redhat.com/security/cve/CVE-2023-5841 https://bugzilla.redhat.com/show_bug.cgi?id=2262397 • CWE-122: Heap-based Buffer Overflow CWE-787: Out-of-bounds Write •
CVE-2021-45942
https://notcve.org/view.php?id=CVE-2021-45942
OpenEXR 3.1.x before 3.1.4 has a heap-based buffer overflow in Imf_3_1::LineCompositeTask::execute (called from IlmThread_3_1::NullThreadPoolProvider::addTask and IlmThread_3_1::ThreadPool::addGlobalTask). NOTE: db217f2 may be inapplicable. OpenEXR versión 3.1.x anterior a la versión 3.1.4 tiene un desbordamiento de búfer basado en la pila en Imf_3_1::LineCompositeTask::execute (llamado desde IlmThread_3_1::NullThreadPoolProvider::addTask e IlmThread_3_1::ThreadPool::addGlobalTask).

CVE-2021-3941
https://notcve.org/view.php?id=CVE-2021-3941
In ImfChromaticities.cpp routine RGBtoXYZ(), there are some division operations such as `float Z = (1 - chroma.white.x - chroma.white.y) * Y / chroma.white.y;` and `chroma.green.y * (X + Z))) / d;` but the divisor is not checked for a 0 value. A specially crafted file could trigger a divide-by-zero condition which could affect the availability of programs linked with OpenEXR. En la rutina RGBtoXYZ() del archivo ImfChromaticities.cpp, se presentan algunas operaciones de división como "float Z = (1 - chroma.white.x - chroma.white.y) * Y / chroma.white.y;" y "chroma.green.y * (X + Z)) / d;" pero no es comprobado que el divisor tenga un valor 0. Un archivo especialmente diseñado podría desencadenar una condición de división por cero que podría afectar a la disponibilidad de los programas enlazados con OpenEXR • https://bugzilla.redhat.com/show_bug.cgi?id=2019789 https://lists.debian.org/debian-lts-announce/2022/12/msg00022.html https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/I2JSMJ7HLWFPYYV7IAQZD5ZUUUN7RWBN https://security.gentoo.org/glsa/202210-31 https://www.debian.org/security/2022/dsa-5299 • CWE-369: Divide By Zero •
CVE-2021-3933
https://notcve.org/view.php?id=CVE-2021-3933
An integer overflow could occur when OpenEXR processes a crafted file on systems where size_t < 64 bits. This could cause an invalid bytesPerLine and maxBytesPerLine value, which could lead to problems with application stability or lead to other attack paths. Podría producirse un desbordamiento de enteros cuando OpenEXR procesa un archivo diseñado en sistemas donde size_t es menor a 64 bits. Esto podría causar un valor no válido de bytesPerLine y maxBytesPerLine, lo que podría conllevar a problemas con la estabilidad de la aplicación o conducir a otras vías de ataque • https://bugzilla.redhat.com/show_bug.cgi?id=2019783 https://lists.debian.org/debian-lts-announce/2022/12/msg00022.html https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/I2JSMJ7HLWFPYYV7IAQZD5ZUUUN7RWBN https://security.gentoo.org/glsa/202210-31 https://www.debian.org/security/2022/dsa-5299 • CWE-190: Integer Overflow or Wraparound •
