xvfb-run 1.6.1 in Debian GNU/Linux, Ubuntu, Fedora 10, and possibly other operating systems place the magic cookie (MCOOKIE) on the command line, which allows local users to gain privileges by listing the process and its arguments.
The Ubuntu clamav-milter.init script in clamav-milter before 0.95.1+dfsg-1ubuntu1.2 in Ubuntu 9.04 sets the ownership of the current working directory to the clamav account, which might allow local users to bypass intended access restrictions via read or write operations involving this directory.
nm-applet.conf in GNOME NetworkManager before 0.7.0.99 contains an incorrect deny setting, which allows local users to discover (1) network connection passwords and (2) pre-shared keys via calls to the GetSecrets method in the dbus request handler.
The ntfs-3g package before 1.913-2.fc7 in Fedora 7, and an ntfs-3g package in Ubuntu 7.10/Gutsy, assign incorrect permissions (setuid root) to mount.ntfs-3g, which allows local users with fuse group membership to read from and write to arbitrary block devices, possibly involving a file descriptor leak.
A regression error in tcp-wrappers 7.6.dbs-10 and 7.6.dbs-11 might allow remote attackers to bypass intended access restrictions when a service uses libwrap but does not specify server connection information.
