"The version of python-pillow installed on the remote host is prior to 2.0.0-23.gitd1c6db8. It is, therefore, affected by
multiple vulnerabilities as referenced in the ALAS2-2023-2286 advisory.

  - The (1) load_djpeg function in JpegImagePlugin.py, (2) Ghostscript function in EpsImagePlugin.py, (3) load
    function in IptcImagePlugin.py, and (4) _copy function in Image.py in Python Image Library (PIL) 1.1.7 and
    earlier and Pillow before 2.3.1 do not properly create temporary files, which allow local users to
    overwrite arbitrary files and obtain sensitive information via a symlink attack on the temporary file.
    (CVE-2014-1932)

  - The (1) JpegImagePlugin.py and (2) EpsImagePlugin.py scripts in Python Image Library (PIL) 1.1.7 and
    earlier and Pillow before 2.3.1 uses the names of temporary files on the command line, which makes it
    easier for local users to conduct symlink attacks by listing the processes. (CVE-2014-1933)

  - Python Image Library (PIL) 1.1.7 and earlier and Pillow 2.3 might allow remote attackers to execute
    arbitrary commands via shell metacharacters in unspecified vectors related to CVE-2014-1932, possibly
    JpegImagePlugin.py. (CVE-2014-3007)

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