Description

The remote host is affected by the vulnerability described in GLSA-201312-10 (libsmi: Arbitrary code execution)

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.
