Gentoo Linux Security Advisory

Title: Net-SNMP: Insecure RPATH (GLSA 200509-05)
Severity: normal
Exploitable: local
Date: September 06, 2005
Updated: May 22, 2006
Bug(s): #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: net-analyzer/net-snmp
Vulnerable: < 5.2.1.2-r1
Unaffected: >= 5.2.1.2-r1
Architectures: 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:
Code:
# emerge --sync
    # emerge --ask --oneshot --verbose ">=net-analyzer/net-snmp-5.2.1.2-r1"
