1. 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
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.
