Out-of-bounds write RCE in Adobe Acrobat and Reader 3D content handling
CVE-2019-7120 is a critical memory corruption vulnerability in Adobe Acrobat and Reader affecting DC/Continuous, 2017 Classic, and 2015 Classic releases prior to the vendor-fixed versions. The issue is described by Adobe as an out-of-bounds write and is associated with processing embedded 3D PDF content, specifically the U3D/ECMA-363 handling path involving components such as 2d.x3d and rt3d.dll. Available analysis indicates the vulnerable path can be reached through crafted U3D texture resource metadata that references external texture images; a proof of concept used manipulated texture metadata and an external image reference ending in .iff to trigger memory corruption during image parsing. Crash analysis referenced functions including png_set_filter_heuristics, TIF::Read, _LoadILBM, IFFImport, and rt3d processing routines such as FILETYPE::Func2d, PrepareRescale, GetPicture, and EndPicturesCache. Successful exploitation could result in arbitrary code execution.
