ppc64-diag 2.6.1 allows local users to overwrite arbitrary files via a symlink attack related to (1) rtas_errd/diag_support.c and /tmp/get_dt_files, (2) scripts/ppc64_diag_mkrsrc and /tmp/diagSEsnap/snapH.tar.gz, or (3) lpd/test/lpd_ela_test.sh and /var/tmp/ras.
Improper Link Resolution Before File Access The product attempts to access a file based on the filename, but it does not properly prevent that filename from identifying a link or shortcut that resolves to an unintended resource.
