Gentoo Linux Security Advisory

Title: libsmi: Arbitrary code execution (GLSA 201312-10)
Severity: normal
Exploitable: local, remote
Date: December 14, 2013
Bug(s): #342127
ID: 201312-10

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: net-libs/libsmi
Vulnerable: < 0.4.8-r1
Unaffected: >= 0.4.8-r1
Architectures: All supported architectures


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:
Code:
# 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.
