Sun recommends that you install the patches listed in section 4 immediately on systems running SunOS 5.8_x86, 5.7_x86, and 5.6_x86. or Trusted Solaris 8_x86 and 7_x86. 2. Who is Affected Vulnerable: Intel Platform Edition of Solaris 8, 7, and 2.6 (SunOS 5.8_x86, 5.7_x86, and 5.6_x86). Intel Platform Edition of Trusted Solaris 8 and 7. Not vulnerable: All SPARC Platform Editions of Solaris and Intel Platform Editions of Solaris prior to 2.6. 3.
