Title: Perl, Qt-UnixODBC, CMake: RUNPATH issues (GLSA 200510-14)
Severity: low
Exploitable: local
Date: October 17, 2005
Updated: May 22, 2006
Bug(s): #105719, #105721, #106678
ID: 200510-14

Synopsis

Multiple packages suffer from RUNPATH issues that may allow users in the "portage" group to escalate privileges.

Background

Perl is a stable, cross-platform programming language created by Larry Wall. Qt-UnixODBC is an ODBC library for Qt. CMake is a cross-platform build environment.

Affected Packages

Package: dev-lang/perl
Vulnerable: < 5.8.7-r1
Unaffected: >= 5.8.7-r1
Unaffected: >= 5.8.6-r6 < 5.8.7
Architectures: All supported architectures

Package: dev-db/qt-unixODBC
Vulnerable: < 3.3.4-r1
Unaffected: >= 3.3.4-r1
Architectures: All supported architectures

Package: dev-util/cmake
Vulnerable: < 2.2.0-r1
Unaffected: >= 2.2.0-r1
Unaffected: >= 2.0.6-r1 < 2.0.7
Architectures: All supported architectures


Description

Some packages may introduce insecure paths into the list of directories that are searched for libraries at runtime. Furthermore, packages depending on the MakeMaker Perl module for build configuration may have incorrectly copied the LD_RUN_PATH into the DT_RPATH.

Impact

A local attacker, who is a member of the "portage" group, could create a malicious shared object in the Portage temporary build directory that would be loaded at runtime by a dependent executable, potentially resulting in privilege escalation.

Workaround

Only grant "portage" group rights to trusted users.

Resolution

All Perl users should upgrade to the latest version:
