Bulletins Topics Sun announces the release of patches for Solaris(tm) 2.6, 2.5.1, 2.5, 2.4, and 2.3 (SunOS(tm) 5.6, 5.5.1, 5.5, 5.4, and 5.3), which relate to a vulnerability in the rpcbind program. Sun recommends that you install the patches listed in section 4 immediately on systems running SunOS 5.6, 5.5.1, 5.5, 5.4, and 5.3. 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, 5.4_x86, and 5.3. Not vulnerable: All other supported versions of SunOS. 3. Understanding the Vulnerability The rpcbind program is a server that converts RPC program numbers into universal addresses. When an RPC service is started, it registers itself with rpcbind by telling rpcbind the address at which the RPC service is listening, and the RPC program numbers it is prepared to serve. A vulnerability has been discovered in rpcbind which, if exploited, can be used to overwrite arbitrary files and permit unauthorized system access. 4. List of Patches The following patches are available in relation to the above problem.
