1. Bulletins Topics
This issue is only present on the Intel Platform Edition of
Solaris.
Sun announces the release of patches for Intel Platform Editions
of Solaris(tm) 8, 7, and 2.6 (SunOS(tm) 5.8_x86, 5.7_x86, and 5.6_x86)
which relate to a vulnerability in user-supplied arguments to a syscall
on i386 platforms.
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. Understanding the Vulnerability
The Intel i386 architecture supports a protection and segmentation
model which allows different levels of privilege. Carefully
constructed arguments could allow access to higher privilege than
intended which could be used to control arbitrary addresses in kernel
memory.
4. List of Patches
The following patches are available in relation to the above problems.
