Aladdin Enterprises Ghostscript 5.10cl

The (1) pj-gs.sh, (2) ps2epsi, (3) pv.sh, and (4) sysvlp.sh scripts in the ESP Ghostscript (espgs) package in Trustix Secure Linux 1.5 through 2.1, and other operating systems, allow local users to overwrite files via a symlink attack on temporary files.

ghostscript before 5.10-16 uses an empty LD_RUN_PATH environmental variable to find libraries in the current directory, which could allow local users to execute commands as other users by placing a Trojan horse library into a directory from which another user executes ghostscript.
