Detail

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.

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.

Id Description
68767 libsmi lib/smi.c smiGetNode() Function Object Identifier (OID) Handling Overflow

libsmi is prone to an overflow condition. The 'smiGetNode' function in 'lib/smi.c' fails to properly sanitize user-supplied input resulting in a stack-based buffer overflow. With a specially crafted overly long string in an Object Identifier, a context-dependent attacker can potentially execute arbitrary code.
