Heap-based buffer overflow in the ReadDIB function in the Vcl.Graphics.TPicture.Bitmap implementation in the Visual Component Library (VCL) in Embarcadero Delphi XE6 20.0.15596.9843 and C++ Builder XE6 20.0.15596.9843 allows context-dependent attackers to execute arbitrary code via the BITMAPINFOHEADER.biClrUsed field in a BMP file. NOTE: this vulnerability exists because of an incomplete fix for CVE-2014-0993.
The product performs operations on a memory buffer, but it reads from or writes to a memory location outside the buffer's intended boundary. This may result in read or write operations on unexpected memory locations that could be linked to other variables, data structures, or internal program data.
