The Xsession script, as used by X Display Manager (xdm) in NetBSD before 20060212, X.Org before 20060317, and Solaris 8 through 10 before 20061006, allows local users to overwrite arbitrary files, or read another user's Xsession errors file, via a symlink attack on a /tmp/xses-$USER file.
Unknown vulnerability in the Basic Security Module (BSM), when configured to audit either the Administrative (ad) or the System-Wide Administration (as) audit class in Solaris 7, 8, and 9, allows local users to cause a denial of service (kernel panic).
