A Common Vulnerability Scoring System base score, which gives a detailed severity rating, is available from the CVE link in the References section. Description Ghostscript is a set of software that provides a PostScript interpreter, a set of C procedures and an interpreter for Portable Document Format files. An integer overflow flaw, leading to a heap-based buffer overflow, was found in Ghostscript"s International Color Consortium Format library .
