libsmi: Arbitrary code execution


1.  Gentoo Linux Security Advisory

Version Information

Advisory Reference GLSA 201312-10 / libsmi
Release Date December 14, 2013
Latest Revision December 14, 2013: 1
Impact normal
Exploitable local, remote
Package Vulnerable versions Unaffected versions Architecture(s)
net-libs/libsmi < 0.4.8-r1 >= 0.4.8-r1 All supported architectures

Related bugreports: #342127


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

2.  Impact Information


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


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


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

3.  Resolution Information


There is no known workaround at this time.


All libsmi users should upgrade to the latest version:

Code Listing 3.1: Resolution

  # 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.
