Ubuntu: Security Vulnerabilities
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.

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.

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 postfix.postinst script in the Debian GNU/Linux and Ubuntu postfix 2.5.5 package grants the postfix user write access to /var/spool/postfix/pid, which might allow local users to conduct symlink attacks that overwrite arbitrary files.

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.
