Synopsis
========

A buffer overflow in libsmi might allow a context-dependent attacker to
execute arbitrary code.

Background
==========

libsmi is a library that allows management applications to access SMI
MIB module definitions.

Affected packages
=================

    -------------------------------------------------------------------
     Package              /     Vulnerable     /            Unaffected
    -------------------------------------------------------------------
  1  net-libs/libsmi             < 0.4.8-r1               >= 0.4.8-r1

Description
===========

libsmi contains a buffer overflow vulnerability in the smiGetNode()
function in lib/smi.c.

Impact
======

A context-dependent attacker could possibly execute arbitrary code by
way of a specially crafted Object Identifier (OID).

Workaround
==========

There is no known workaround at this time.

Resolution
==========

All libsmi users should upgrade to the latest version:

  # emerge --sync
  # emerge --ask --oneshot --verbose ">=net-libs/libsmi-0.4.8-r1"

Packages which depend on this library may need to be recompiled. Tools
such as revdep-rebuild may assist in identifying these packages.

NOTE: This is a legacy GLSA. Updates for all affected architectures are
available since October 30, 2010. It is likely that your system is
already no longer affected by this issue.
