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
-------------------------------------------------------------------
1 net-analyzer/net-snmp < 5.2.1.2-r1 >= 5.2.1.2-r1
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"
Availability
============
This GLSA and any updates to it are available for viewing at
the Gentoo Security Website:
