FreeBSD : libsmi -- Buffer overflow in the smiGetNode function in lib/smi (76b09b16-638b-11f1-8e16-901b0e13f1a0)

critical Nessus Plugin ID 321092

Synopsis

The remote FreeBSD host is missing one or more security-related updates.

Description

The version of FreeBSD installed on the remote host is prior to tested version. It is, therefore, affected by a vulnerability as referenced in the 76b09b16-638b-11f1-8e16-901b0e13f1a0 advisory.

http://lists.opensuse.org/opensuse-security-announce/2011-01/msg00003.html reports:
Buffer overflow in the smiGetNode function in lib/smi.c in libsmi 0.4.8 allows context-dependent attackers to execute arbitrary code via an Object Identifier (aka OID) represented as a numerical string containing many components separated by . (dot) characters.

Tenable has extracted the preceding description block directly from the FreeBSD security advisory.

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

Solution

Update the affected packages.
