OpenSSH 4.3p2, and probably other versions, allows local users to hijack forwarded X connections by causing ssh to set DISPLAY to :10, even when another process is listening on the associated port, as demonstrated by opening TCP port 6010 (IPv4) and sniffing a cookie sent by Emacs.
Eterm 0.9.4 opens a terminal window on :0 if -display is not specified and the DISPLAY environment variable is not set, which might allow local users to hijack X11 connections. NOTE: realistic attack scenarios require that the victim enters a command on the wrong machine.
The script program in FreeBSD 5.0 through 7.0-PRERELEASE invokes openpty, which creates a pseudo-terminal with world-readable and world-writable permissions when it is not run as root, which allows local users to read data from the terminal of the user running script.
PostgreSQL 8.1 and probably later versions, when local trust authentication is enabled and the Database Link library (dblink) is installed, allows remote attackers to access arbitrary accounts and execute arbitrary SQL queries via a dblink host parameter that proxies the connection from 127.0.0.1.
Buffer overflow in Macrovision SafeDisc secdrv.sys before 4.3.86.0, as shipped in Microsoft Windows XP SP2, XP Professional x64 and x64 SP2, Server 2003 SP1 and SP2, and Server 2003 x64 and x64 SP2 allows local users to overwrite arbitrary memory locations and gain privileges via a crafted argument to a METHOD_NEITHER IOCTL, as originally discovered in the wild.
ZoneAlarm Pro 7.0.362.000 does not properly validate certain parameters to System Service Descriptor Table (SSDT) function handlers, which allows local users to cause a denial of service (crash) and possibly gain privileges via the (1) NtCreatePort and (2) NtDeleteFile kernel SSDT hooks, a partial regression of CVE-2007-2083.
Untrusted search path vulnerability in db2pd in IBM DB2 Universal Database (UDB) 8 before FixPak 16 and 9 before Fix Pack 4 allows local users to gain root privileges via a modified DB2INSTANCE environment variable that points to a malicious library. NOTE: this might be the same issue as CVE-2008-0697.
PHP before 5.2.5 allows local users to bypass protection mechanisms configured through php_admin_value or php_admin_flag in httpd.conf by using ini_set to modify arbitrary configuration variables, a different issue than CVE-2006-4625.
