     * Sun Alert ID: 57509
     * Synopsis: Security Vulnerability in "/usr/lib/print/conv_fix" May
       Allow Unauthorized Privileges and/or Denial of Service

1. Impact

   The "/usr/lib/print/conv_fix" command is invoked by the conv_lpd(1M)
   script and contains a security vulnerability. If the conv_lpd(1M)
   script is executed as the "root" user, it may be possible for
   unprivileged local users to exploit this vulnerability to overwrite or
   create any file on the system. This could lead to unauthorized
   elevated privileges or allow a Denial of Service (DoS) against the
   system.
   
2. Contributing Factors

   This issue can occur in the following releases:
   
   SPARC Platform
     * Solaris 7 without patch 107115-14
     * Solaris 8 without patch 109320-09
     * Solaris 9 without patch 113329-05
       
   x86 Platform
     * Solaris 7 without patch 107116-14
     * Solaris 8 without patch 109321-09
     * Solaris 9 without patch 114980-05
       
3. Symptoms

   There are no reliable symptoms that would indicate the described issue
   has been exploited, as it depends on which file is overwritten or
   created.
   SOLUTION SUMMARY:
   
4. Relief/Workaround

   To work around the described issue, run conv_lpd(1M) as a non-root
   user.
