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: http://www.cert.org/advisories/CA-2001-31.html 4.
