Bugs

#342127

Advisory

https://security.gentoo.org/glsa/201312-10

Affected packages

Package	Arch	Vulnerable	Unaffected
net-libs/libsmi	*	< 0.4.8-r1	>= 0.4.8-r1

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).

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.
