obby (aka libobby) does not verify SSL server certificates, which allows remote attackers to spoof servers via an arbitrary certificate.

The X.Org X wrapper (xserver-wrapper.c) in Debian GNU/Linux and Ubuntu Linux does not properly verify the TTY of a user who is starting X, which allows local users to bypass intended access restrictions by associating stdin with a file that is misinterpreted as the console TTY.

language-selector 0.110.x before 0.110.1, 0.90.x before 0.90.1, and 0.79.x before 0.79.4 does not properly use D-Bus for communication with a polkit authority, which allows local users to bypass intended access restrictions by leveraging a PolkitUnixProcess PolkitSubject race condition via a (1) setuid process or (2) pkexec process, a related issue to CVE-2013-4288.

dbus_backend/lsd.py in the D-Bus backend in language-selector before 0.6.7 does not validate the arguments to the (1) SetSystemDefaultLangEnv and (2) SetSystemDefaultLanguageEnv functions, which allows local users to gain privileges via shell metacharacters in a string argument, a different vulnerability than CVE-2011-0729.

dbus_backend/ls-dbus-backend in the D-Bus backend in language-selector before 0.6.7 does not restrict access on the basis of a PolicyKit check result, which allows local users to modify the /etc/default/locale and /etc/environment files via a (1) SetSystemDefaultLangEnv or (2) SetSystemDefaultLanguageEnv call.

The Live DVD for Edubuntu 9.10, 10.04 LTS, and 10.10 does not correctly regenerate iTALC private keys after installation, which causes each installation to have the same fixed key, which allows remote attackers to gain privileges.

The base-files package before 5.0.0ubuntu7.1 on Ubuntu 9.10 and before 5.0.0ubuntu20.10.04.2 on Ubuntu 10.04 LTS, as shipped on Dell Latitude 2110 netbooks, does not require authentication for package installation, which allows remote archive servers and man-in-the-middle attackers to execute arbitrary code via a crafted package.

The eCryptfs support utilities (ecryptfs-utils) 73-0ubuntu6.1 on Ubuntu 9.04 stores the mount passphrase in installation logs, which might allow local users to obtain access to the filesystem by reading the log files from disk. NOTE: the log files are only readable by root.

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.

system-tools-backends before 2.6.0-1ubuntu1.1 in Ubuntu 8.10, as used by "Users and Groups" in GNOME System Tools, hashes account passwords with 3DES and consequently limits effective password lengths to eight characters, which makes it easier for context-dependent attackers to successfully conduct brute-force password attacks.
