DOCUMENT ID: 56300
SYNOPSIS: Solaris 2.6 and 7 cachefs Patches May Overwrite the
inetd.conf(4) File
DETAIL DESCRIPTION:
Sun(sm) Alert Notification
* Sun Alert ID: 56300
* Synopsis: Solaris 2.6 and 7 cachefs Patches May Overwrite the
inetd.conf(4) File
* Category: Security
* Product: Solaris
* BugIDs: 4839365
* Avoidance: Patch
* State: Resolved
* Date Released: 18-Aug-2003
* Date Closed: 18-Aug-2003
* Date Modified:
1. Impact
On Solaris 2.6 and Solaris 7 systems, the inetd.conf(4) file may get
erroneously overwritten during installation of certain cachefs
patches. The resulting new "inetd.conf" file may re-enable services
that were previously disabled (e.g. for security reasons).
2. Contributing Factors
This issue can occur in the following releases:
SPARC Platform
* Solaris 2.6 with patch 105693-13 and without patch 105693-14
* Solaris 7 with patch 108800-02 and without patch 108800-03
x86 Platform
* Solaris 2.6 with patch 105694-13 and without patch 105694-14
* Solaris 7 with patch 108801-02 and without patch 108801-03
Note: Solaris 8 and 9 are not affected by this issue. The cachefs
patches are part of the current "Recommended & Security Patches"
cluster.
3. Symptoms
After installation of one of the above listed patches, some services
may be enabled which were previously disabled. The symptoms
experienced will depend upon which services had been disabled.
SOLUTION SUMMARY:
4. Relief/Workaround
To work around the described issue, make a backup copy of the existing
inetd.conf(4) file before installing the cachefs patches and then
restore the inetd.conf(4) file after patch installation. For example:
# cp /etc/inet/inetd.conf /etc/inetd/inetd.conf.prepatch
# patchadd <cachefs patch>
# cp /etc/inet/inetd.conf.prepatch /etc/inetd/inetd.conf
If the Solaris 2.6 or 7 cachefs patches have already been installed on
the system, review the inetd.conf(4) file for entries which may have
been changed by the patch installation.
5. Resolution
This issue is addressed in the following releases:
SPARC Platform
* Solaris 2.6 with patch 105693-14 or later
* Solaris 7 with patch 108800-03 or later
x86 Platform
* Solaris 2.6 with patch 105694-14 or later
* Solaris 7 with patch 108801-03 or later
