Bulletins Topics Sun announces the release of patches for Solaris(tm) 7, 2.6, 2.5.1, 2.5, 2.4, and 2.3 (SunOS(tm) 5.7, 5.6, 5.5.1, 5.5, 5.4 and 5.3), which relate to a vulnerability with sadmind. Sun recommends that you install the patches listed in section 4 immediately on systems running SunOS 5.7, 5.6, 5.5.1, and 5.5 and on systems with Solstice AdminSuite (AdminSuite) installed. If you have installed a version of AdminSuite prior to version 2.3, please upgrade to AdminSuite 2.3 before installing the AdminSuite patches listed in section 4. Sun also recommends that you: - disable sadmind if you do not use it by commenting the following line in /etc/inetd.conf: 100232/10 tli rpc/udp wait root /usr/sbin/sadmind sadmind - set the security level used to authenticate requests to STRONG as follows, if you use sadmind: 100232/10 tli rpc/udp wait root /usr/sbin/sadmind sadmind -S 2 The above changes to /etc/inetd.conf will take effect after inetd receives a hang-up signal. 2. Who is Affected Vulnerable: SunOS 5.7, 5.7_x86, 5.6, 5.6_x86, 5.5.1, 5.5.1_x86, 5.5, 5.5_x86, and 5.4, 5.4_x86, and 5.3 with AdminSuite installed Not vulnerable: All other supported versions of SunOS. 3. Understanding the Vulnerability The sadmind program is installed by default on SunOS 5.7, 5.6, 5.5.1, and 5.5. In SunOS 5.4 and 5.3, sadmind may be installed if the Solstice AdminSuite packages are installed. The sadmind program is installed in /usr/sbin. The program can be used to perform distributed system administration operations remotely. A buffer overflow vulnerability has been discovered in sadmind which may be exploited by a remote attacker to execute arbitrary instructions and gain root access. 4. List of Patches The following patches are available in relation to the above problem.
