1. Bulletins Topics
Sun announces the release of patches for Solaris(tm) 8, 7, 2.6,
and 2.5.1 (SunOS(tm) 5.8, 5.7, 5.6, and 5.5.1) which relate to a
buffer overflow in dtspcd.
Sun recommends that you install the patches listed in section 4
immediately on systems running the CDE Subprocess control service,
dtspcd, on SunOS 5.8, 5.7, 5.6, and 5.5.1.
2. Who is Affected
Vulnerable: SunOS 5.8, 5.8_x86, 5.7, 5.7_x86, 5.6,
5.6_x86, 5.5.1, and 5.5.1_x86
3. Understanding the Vulnerability
The CDE Subprocess Control Service (dtspcd) daemon accepts requests
from CDE clients to execute commands and launch applications on the
local system running the dtspcd daemon. The dtspcd daemon is spawned
by the inetd daemon (see inetd(1M)) in response to a CDE client
request. dtspcd is normally configured to run on port 6112/tcp with
root privileges.
A buffer overflow has been discovered in dtspcd which may be
exploited by a local or a remote attacker to gain root access on the
affected system. Any system that does not run the CDE Subprocess
Control service, dtspcd, is not vulnerable to this problem. This
issue was discovered by ISS X-Force who published an advisory at:
http://xforce.iss.net/alerts/advise101.php
CERT Advisory CA-2001-31 is available from:
