Security Vulnerabilities in Solaris Print Service

1. Impact

Security vulnerabilities in the Solaris print service may allow a remote unprivileged user the ability to run arbitrary code as root or  cause  a Denial of Service (DoS) condition.

2. Contributing Factors

These issues can occur in the following releases:

SPARC Platform

• Solaris 8 without patch 109320-20
  
• Solaris 9 without patch 113329-19
  
• Solaris 10 without patch 126672-02

x86 Platform

• Solaris 8 without patch 109321-20
  
• Solaris 9 without patch 114980-20
  
• Solaris 10 without patch 126673-02

3. Symptoms

If the issue described in BugID 6599950 occurs, users may experience a DoS condition on the Solaris print system.

There are no predictable symptoms that would indicate the described issue has been exploited to execute arbitrary code.

4. Workaround

To work around the described issues, do the following:

For Solaris 8 and Solaris 9 Systems:

Disable the BSD print protocol adaptor (in.lpd(1M)) by doing the following:

1. Edit the "/etc/inetd.conf" file and comment out the following line by adding the "#" symbol to the beginning of the line as shown:
    #printer stream tcp6 nowait root /usr/lib/print/in.lpd in.lpd

2. Tell the inetd(1M) process to reread the newly modified "/etc/inetd.conf" file by sending it a hangup signal, SIGHUP:

    # /usr/bin/pkill -HUP inetd

For Solaris 10 Systems:

Disable the main print services by executing the following commands:

    # svcadm disable svc:/application/print/rfc1179
    # svcadm disable svc:/application/print/ipp-listener
    # svcadm disable svc:/application/print/server

5. Resolution

These issues are addressed in the following releases:

SPARC Platform

• Solaris 8 with patch 109320-20 or later
  
• Solaris 9 with patch 113329-19 or later
  
• Solaris 10 with patch 126672-02 or later
  

x86 Platform

• Solaris 8 with patch 109321-20 or later
  
• Solaris 9 with patch 114980-20 or later
  
• Solaris 10 with patch 126673-02 or later
