Impact Local unprivileged users may be able to start processes on non-privileged network ports. By "stealing" the port, these processes may act as modified or "trojaned" versions of the service that typically runs on that port. This condition could lead to service disruption, a sensitive information leak, or possible compromise of remote systems. Note: This issue only applies to network services which run on non-privileged ports such as NFS or NIS, and network server systems which allow user logins. 2. Contributing Factors This issue can occur in the following releases: SPARC Platform Solaris 8 without patch 116965-08 Solaris 9 without patch 118305-02 x86 Platform Solaris 8 without patch 116966-08 Solaris 9 without patch 117470-01 Note: Solaris 7 and Solaris 10 are unaffected by this issue. 3. Symptoms Depending on the "trojan" that has been installed, there may be no obvious symptoms to indicate this issue has occurred. It is possible that services such as NIS may stop working for no apparent reason. Solution Summary Top 4. Relief/Workaround There is no workaround. Please see the "Resolution" section below. 5. Resolution This issue is addressed in the following releases: SPARC Platform Solaris 8 with patch 116965-08 or later Solaris 9 with patch 118305-02 or later x86 Platform Solaris 8 with patch 116966-08 or later Solaris 9 with patch 117470-01 or later This Sun Alert notification is being provided to you on an "AS IS" basis.
