"The remote NewStart CGSL host, running version MAIN 6.06, has ghostscript packages installed that are affected by
multiple vulnerabilities:

  - A trivial sandbox (enabled with the `-dSAFER` option) escape flaw was found in the ghostscript interpreter
    by injecting a specially crafted pipe command. This flaw allows a specially crafted document to execute
    arbitrary commands on the system in the context of the ghostscript interpreter. The highest threat from
    this vulnerability is to confidentiality, integrity, as well as system availability. (CVE-2021-3781)

  - The jpc_qcx_getcompparms function in jpc/jpc_cs.c for the JasPer JPEG-2000 library (libjasper) before
    1.900 allows remote user-assisted attackers to cause a denial of service (crash) and possibly corrupt the
    heap via malformed image files, as originally demonstrated using imagemagick convert. (CVE-2007-2721)

  - Stack-based buffer overflow in the zseticcspace function in zicc.c in Ghostscript 8.61 and earlier allows
    remote attackers to execute arbitrary code via a postscript (.ps) file containing a long Range array in a
    .seticcspace operator. (CVE-2008-0411)

  - Heap-based buffer overflow in the big2_decode_symbol_dict function (jbig2_symbol_dict.c) in the JBIG2
    decoding library (jbig2dec) in Ghostscript 8.64, and probably earlier versions, allows remote attackers to
    execute arbitrary code via a PDF file with a JBIG2 symbol dictionary segment with a large run length
    value. (CVE-2009-0196)

  - Multiple integer overflows in icc.c in the International Color Consortium (ICC) Format library (aka
    icclib), as used in Ghostscript 8.64 and earlier and Argyll Color Management System (CMS) 1.0.3 and
    earlier, allow context-dependent attackers to cause a denial of service (heap-based buffer overflow and
    application crash) or possibly execute arbitrary code by using a device file for a translation request
    that operates on a crafted image file and targets a certain native color space, related to an ICC
    profile in a (1) PostScript or (2) PDF file with embedded images. (CVE-2009-0583)

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version
number.");
