Solaris 8 Operating System

Bug Id
4457722

Date of Resolved Release
21-JUL-2003

Impact

Solaris 8 systems configured to use Internet Protocol Version 6 (ip6(7P)) may panic when processing certain IPv6 packets. A local or remote user may be able to send IPv6 packets which would panic the system causing a Denial of Service.

Contributing Factors

This issue can occur in the following releases:

SPARC Platform

• Solaris 8 without patch 108528-21

x86 Platform

• Solaris 8 without patch 108529-21

Note: Solaris 2.6, Solaris 7 and Solaris 9 are not impacted by this issue.

Symptoms

The symptom of this issue is a system panic.

Workaround

To work around the described issue, disable IPv6 on the system.

To determine if a system is running with IPv6 enabled, run the following command:

    $ ifconfig -a6

If entries are printed marked "UP and RUNNING" then the system is utilizing IPv6.

To disable IPv6 on a system, run the following command as root:

    # ifconfig -a6 down

Edit the "/etc/nsswitch.conf" file and change the ipnodes entry to be "files" only. IPv6 will function again after a reboot.

Note: To disable IPv6 on systems across a system reboot, the "/etc/hostname6.<interface>" files can be temporarily renamed.

Resolution

This issue is addressed in the following releases:

SPARC Platform

• Solaris 8 with patch 108528-21 or later

x86 Platform

• Solaris 8 with patch 108529-21 or later
