Sun(sm) Alert Notification
* Sun Alert ID: 57766
* Synopsis: Certain Network Services Disruptions or "Spoofs" Could
Occur as a Result of Possible Network Port Theft
* Category: Security
* Product: Solaris
* BugIDs: 5089150
* Avoidance: Patch
* State: Resolved
* Date Released: 18-Apr-2005
* Date Closed: 18-Apr-2005
* Date Modified:
1. 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 [2]116965-08
* Solaris 9 without patch [3]118305-02
x86 Platform
* Solaris 8 without patch [4]116966-08
* Solaris 9 without patch [5]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.
