Mandriva Linux Security Advisory MDVSA-2013:086
http://www.mandriva.com/en/support/security/
_______________________________________________________________________

Package : groff
Date : April 9, 2013
Affected: Business Server 1.0
_______________________________________________________________________

Problem Description:

Multiple vulnerabilities has been found and corrected in groff:

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) 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
(CVE-2009-5079).

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).

The updated packages have been patched to correct these issues.
