| Doc Text: |
There's a flaw in OpenEXR's deep tile sample size calculations. An attacker who is able to submit a crafted file to be processed by OpenEXR could trigger an integer overflow, subsequently leading to an out-of-bounds read. The greatest risk of this flaw is to application availability.

External References: https://bugs.chromium.org/p/oss-fuzz/issues/detail?id=26956 Created OpenEXR tracking bugs for this issue: Affects: fedora-all [bug 1939185] I *believe* this is the upstream patch: https://github.com/AcademySoftwareFoundation/openexr/commit/467be80b75642efbbe6bdace558079f68c16acb1 It is not quite clear from the oss-fuzz output (I don't have access to the "detailed report." Flaw summary: Integer overflow in DeepTiledInputFile::initialize() of src/lib/OpenEXR/ImfDeepTiledInputFile.cpp could lead to an out-of-bounds read in DeepTiledInputFile::readPixelSampleCounts() based on the file's tileDesc.xSize and tileDesc.ySize. This is fixed in OpenEXR v2.5.4, v2.5.5, and v3.0.1 and beyond. This is also fixed in OpenEXR v2.4.3 https://github.com/AcademySoftwareFoundation/openexr/blob/master/CHANGES.md#version-243-may-17-2021 |
