"The remote NewStart CGSL host, running version MAIN 5.04, has groff packages installed that are affected by multiple
vulnerabilities:

  - contrib/pdfmark/pdfroff.sh in GNU troff (aka groff) before 1.21 allows local users to overwrite arbitrary
    files via a symlink attack on a pdf#####.tmp temporary file. (CVE-2009-5044)

  - The (1) contrib/eqn2graph/eqn2graph.sh, (2) contrib/grap2graph/grap2graph.sh, and (3)
    contrib/pic2graph/pic2graph.sh scripts in GNU troff (aka groff) 1.21 and earlier do not properly handle
    certain failed attempts to create temporary directories, which might allow local users to overwrite
    arbitrary files via a symlink attack on a file in a temporary directory, a different vulnerability than
    CVE-2004-1296. (CVE-2009-5080)

  - The (1) config.guess, (2) contrib/groffer/perl/groffer.pl, and (3) contrib/groffer/perl/roff2.pl scripts
    in GNU troff (aka groff) 1.21 and earlier use an insufficient number of X characters in the template
    argument to the tempfile function, which makes it easier for local users to overwrite arbitrary files via
    a symlink attack on a temporary file, a different vulnerability than CVE-2004-0969. (CVE-2009-5081)

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