1. Bulletin Topics

Sun announces the release of patches for Solaris(tm) 7, 2.6, 2.5.1, 2.5,
2.4, 2.3 (SunOS(tm) 5.7, 5.6, 5.5.1, 5.5, 5.4, 5.3), and SunOS 4.1.4,
and 4.1.3_U1 which relate to various vulnerabilities in CDE and
OpenWindows.

Sun recommends that you install the patches listed in section 4
immediately on systems running SunOS 5.7, 5.6, 5.5.1, 5.5, 5.4, 5.3,
4.1.4, and 4.1.3_U1.

2. Who is Affected

Vulnerable: SunOS 5.7, 5.7_x86, 5.6, 5.6_x86, 5.5.1, 5.5, 5.4, 5.3,
4.1.4, and 4.1.3_U1.

Not vulnerable: All other supported versions of SunOS.

3. Understanding the Vulnerabilities

The following vulnerabilities have been identified.

3.1 ToolTalk ttsession default authentication mechanism insecure

The ToolTalk messaging utility, ttsession, allows independent
applications to communicate without having direct knowledge of
each other. The ttsession daemon is started automatically by
any program that needs to send or receive a ToolTalk message. It uses
AUTH_UNIX authentication by default. A local or remote attacker may
manipulate certain environment variables (which are used by ttsession
to determine how client messages are handled) to execute arbitrary
commands with the privileges of the running ttsession.

3.2 CDE dtspcd relies on file-system based authentication

The CDE desktop subprocess control program (dtspcd) is a network
daemon that accepts requests from clients to execute commands and
launch applications remotely. By manipulating predictable files used
for authentication, a local attacker may exploit this vulnerability
to execute arbitrary commands and gain root access.

3.3 CDE dtaction buffer overflow

The dtaction utility allows applications or shell scripts, which are
otherwise not connected into the CDE user environment, to request
CDE actions be performed. A buffer overflow vulnerability has been
discovered which may be exploited by a local attacker to execute
arbitrary instructions and gain root access.

3.4 CDE ToolTalk shared library buffer overflow in TT_SESSION

A buffer overflow vulnerability has been discovered in the ToolTalk
shared library which may be exploited by a local attacker to execute
arbitrary instructions and gain root access.
