The VUPEN Vulnerability Research Team discovered a critical vulnerability in Microsoft Windows. The vulnerability is caused by a stack overflow error in the OpenType Compact Font Format (CFF) driver "ATMFD.dll" when processing certain operands within an OpenType font, which could be exploited by remote attackers to execute arbitrary code on a vulnerable Windows 7, Windows Server 2008, Windows Server 2008 R2, and Windows Vista systems via a malicious font, or by local attackers to gain elevated privileges on Windows XP and Windows Server 2003 systems via a malicious application.

Microsoft Windows Vista/Server 2008 nsiproxy.sys local kernel denial of service exploit.

This Metasploit module exploits a well known remote code execution exploit after establishing encrypted control communications with a Data Protector agent. This allows exploitation of Data Protector agents that have been configured to only use encrypted control communications. This exploit works by executing the payload with Microsoft PowerShell so will only work against Windows Vista or newer. Tested against Data Protector 9.0 installed on Windows Server 2008 R2.

Solaris version 11.4 xscreensaver local privilege escalation exploit.

This Metasploit module exploits a vulnerability in xscreensaver versions since 5.06 on unpatched Solaris 11 systems which allows users to gain root privileges. xscreensaver allows users to create a user-owned file at any location on the filesystem using the -log command line argument introduced in version 5.06. This module uses xscreensaver to create a log file in /usr/lib/secure/, overwrites the log file with a shared object, and executes the shared object using the LD_PRELOAD environment variable. This module has been tested successfully on xscreensaver version 5.15 on Solaris 11.1 (x86) and xscreensaver version 5.15 on Solaris 11.3 (x86).

SunOS version 5.10 Generic_147148-26 local privilege escalation exploit. A buffer overflow in the CheckMonitor() function in the Common Desktop Environment versions 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.

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.

A potential vulnerability with LOGINOUT for OpenVMS (VAX & ALPHA) V7.1 software has been discovered.
