1. Bulletins Topics
Sun announces the release of patches for Solaris(tm) 2.6, 2.5.1,
2.5, and 2.4 (SunOS(tm) 5.6, 5.5.1, 5.5, and 5.4) which relate
to a vulnerability in dtaction.
Sun recommends that you install the patches listed in section 4
immediately on systems running SunOS 5.6, 5.5.1, 5.5, and 5.4
with the Common Desktop Environment (CDE).
2. Who is Affected
Vulnerable: SunOS versions 5.6, 5.6_x86, 5.5.1, 5.5.1_x86, 5.5,
5.5_x86, 5.4, and 5.4_x86 running CDE
Not vulnerable: All other supported versions of SunOS.
3. Understanding the Vulnerability
The dtaction utility allows applications or shell scripts, which are
otherwise not connected into the CDE development environment, to invoke
action requests. Due to insufficient bounds checking on arguments supplied
to dtaction, it is possible to overwrite the internal stack space of
dtaction. As dtaction is setuid root, this vulnerability may be exploited
to gain root access.
4. List of Patches
The following patches are available in relation to the above problem.
