rschiron at redhat dot com changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |rschiron at redhat dot com --- Comment #3 from rschiron at redhat dot com --- Function fs::temp_directory_path() in src/filesystem/ops.cc uses getenv() on TMPDIR/TMP/TEMP/TEMPDIR. Probably secure_getenv() should be used in that case.
