GLSA 201312-10: libsmi: Arbitrary code execution

http://security.gentoo.org/

Severity:	normal
Title:	libsmi: Arbitrary code execution
Date:	12/14/2013
Bugs:	#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	Vulnerable	Unaffected	Architecture(s)
net-libs/libsmi	< 0.4.8-r1	>= 0.4.8-r1	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:

      # 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.
