Sun(sm) Alert Notification

Sun Alert ID: 57659
Synopsis: Security Vulnerability in the in.rwhod(1M) Daemon
Category: Security
Product: Solaris
BugIDs: 4705157
Avoidance: Patch
State: Resolved
Date Released: 06-Dec-2004
Date Closed: 06-Dec-2004
Date Modified:

1. Impact A security vulnerability in the in.rwhod(1M) daemon may allow a remote privileged user to execute arbitrary code with "root" privileges when the in.rwhod(1M) daemon is enabled on the system.

Note: in.rwhod(1M) is not enabled by default.

2. Contributing Factors This issue can occur in the following releases:

SPARC Platform

Solaris 7 without patch 118239-01
Solaris 8 without patch 116984-01
Solaris 9 without patch 117455-01

x86 Platform

Solaris 7 without patch 118240-01
Solaris 8 without patch 116985-01
Solaris 9 without patch 117456-01

A system is only vulnerable to this issue if the in.rwhod(1M) daemon is enabled. This can be determined by using the pgrep(1) command which will only generate output if the daemon is enabled, as in the following example:

    $ pgrep -lf in.rwhod
    17157 /usr/sbin/in.rwhod -m

3. Symptoms There are no predictable symptoms that would indicate the described issue has occurred.
