GNU Groff 1.19

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.

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.

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) 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) 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.

The groffer script in the Groff package 1.18 and later versions, as used in Trustix Secure Linux 1.5 through 2.1, and possibly other operating systems, allows local users to overwrite files via a symlink attack on temporary files.
