Vulnerable code follows: /usr/bin/gnome-subtitles line 9: export LD_LIBRARY_PATH="$libdir/gnome-subtitles:$LD_LIBRARY_PATH" When there's an empty item on the colon-separated list of LD_LIBRARY_PATH, ld.so treats it as '.' (i.e. CWD/$PWD.) If the given script is executed from a directory where a potential, local, attacker can write files to, there's a chance to exploit this bug. Fixed in git: http://git.gnome.org/browse/gnome-subtitles/commit/?id=44370dc2a87f7fa0d6c9730979514bd407a37c65 114166 1 repository-robot 2010-10-23 08:42:29 +0400 gnome-subtitles-1.0-alt1.git.75.gcf1c9d0 -> sisyphus: * Fri Oct 15 2010 Ildar Mulyukov <ildar@altlinux> 1.0-alt1.git.75.gcf1c9d0 - new version - fix CVE-2010-3357 (closes: #24316)
