GNUnet is a peer-to-peer framework with focus on providing security. All peer-to-peer messages in the network are confidential and authenticated. The framework provides a transport abstraction layer and can currently encapsulate the network traffic in UDP (IPv4 and IPv6), TCP (IPv4 and IPv6), HTTP, or SMTP messages. GNUnet supports accounting to provide contributing nodes with better service. The primary service build on top of the framework is anonymous file sharing.

Samhain is a file system integrity checker that can be used as a client/server application for centralized monitoring of networked hosts. Databases and configuration files can be stored on the server. Databases, logs, and config files can be signed for tamper resistance. In addition to forwarding reports to the log server via authenticated TCP/IP connections, several other logging facilities (e-mail, console, and syslog) are available. Tested on Linux, AIX, HP-UX, Unixware, Sun and Solaris.

A low impact information disclosure vulnerability in the setuid root xlock binary distributed with Solaris may allow local users to read partial contents of sensitive files. Due to the fact that target files must be in a very specific format, exploitation of this flaw to escalate privileges in a realistic scenario is unlikely.

A buffer overflow in the CheckMonitor() function in the Common Desktop Environment 2.3.1 and earlier and 1.6 and earlier, as distributed with Oracle Solaris 10 1/13 (Update 11) and earlier, allows local users to gain root privileges via a long palette name passed to dtsession in a malicious .Xdefaults file. Note that Oracle Solaris CDE is based on the original CDE 1.x train, which is different from the CDE 2.x codebase that was later open sourced. Most notably, the vulnerable buffer in the Oracle Solaris CDE is stack-based, while in the open source version it is heap-based.

A buffer overflow in the _SanityCheck() function in the Common Desktop Environment version distributed with Oracle Solaris 10 1/13 (Update 11) and earlier allows local users to gain root privileges via a long calendar name or calendar owner passed to sdtcm_convert in a malicious calendar file. The open source version of CDE (based on the CDE 2.x codebase) is not affected, because it does not ship the vulnerable program. Versions 1.6 and below are affected.

A difficult to exploit stack-based buffer overflow in the _DtCreateDtDirs() function in the Common Desktop Environment version distributed with Oracle Solaris 10 1/13 (Update 11) and earlier may allow local users to corrupt memory and potentially execute arbitrary code in order to escalate privileges via a long X11 display name. The vulnerable function is located in the libDtSvc library and can be reached by executing the setuid program dtsession. Versions 2.3.1 and below as well as 1.6 and earlier are affected.
