GLSA 200509-05: Net-SNMP: Insecure RPATH

http://security.gentoo.org/

Severity:	normal
Title:	Net-SNMP: Insecure RPATH
Date:	09/06/2005
Bugs:	#103776
ID:	200509-05

Synopsis

The Gentoo Net-SNMP package may provide Perl modules containing an insecure DT_RPATH, potentially allowing privilege escalation.

Background

Net-SNMP is a suite of applications used to implement the Simple Network Management Protocol.

Affected packages

Package	Vulnerable	Unaffected	Architecture(s)
net-analyzer/net-snmp	< 5.2.1.2-r1	>= 5.2.1.2-r1	All supported architectures

Description

James Cloos reported that Perl modules from the Net-SNMP package look for libraries in an untrusted location. This is due to a flaw in the Gentoo package, and not the Net-SNMP suite.

Impact

A local attacker (member of the portage group) may be able to create a shared object that would be loaded by the Net-SNMP Perl modules, executing arbitrary code with the privileges of the user invoking the Perl script.

Workaround

Limit group portage access to trusted users.

Resolution

All Net-SNMP users should upgrade to the latest version:

    # emerge --sync
    # emerge --ask --oneshot --verbose ">=net-analyzer/net-snmp-5.2.1.2-r1"
