GHSA-VC68-257W-M432 OpenEXR: Heap information disclosure in PXR24 decompression via unchecked decompressed size (undo_pxr24_impl)

Summary The PXR24 decompression function undopxr24impl in OpenEXR internalpxr24.c ignores the actual decompressed size outSize returned by exruncompressbuffer and instead reads from the scratch buffer based solely on the expected size uncompressedsize derived from the header metadata. Additionall...
