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.

contrib/pdfmark/pdfroff.sh in GNU troff (aka groff) before 1.21 launches the Ghostscript program without the -dSAFER option, which allows remote attackers to create, overwrite, rename, or delete arbitrary files via a crafted document.

The (1) gendef.sh, (2) doc/fixinfo.sh, and (3) contrib/gdiffmk/tests/runtests.in scripts in GNU troff (aka groff) 1.21 and earlier allow local users to overwrite arbitrary files via a symlink attack on a gro#####.tmp or /tmp/##### temporary file.

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.

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.
