Related bugreports: #342127

Synopsis

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

2.  Impact Information

Background

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

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).

3.  Resolution Information

Workaround

There is no known workaround at this time.

Resolution

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.
