Description
In Artifex Ghostscript through 10.01.0, there is a buffer overflow leading to potential corruption of data internal to the PostScript interpreter, in base/sbcp.c. This affects BCPEncode, BCPDecode, TBCPEncode, and TBCPDecode. If the write buffer is filled to one byte less than full, and one then tries to write an escaped character, two bytes are written.

Technical Analysis
Remote code execution in Ghostscript can be exploited by parsing malicious PostScript (EPS) files.
The software is very popular together with ImageMagic, and it’s used to parse uploaded files to generate thumbnails or convert them to different formats.
