Synopsis |
| 16 |
======== |
| 17 |
|
| 18 |
OpenLDAP and Gauche suffer from RUNPATH issues that may allow users in |
| 19 |
the "portage" group to escalate privileges. |
| 20 |
|
| 21 |
Background |
| 22 |
========== |
| 23 |
|
| 24 |
OpenLDAP is a suite of LDAP-related application and development tools. |
| 25 |
Gauche is an R5RS Scheme interpreter. |
| 26 |
|
| 27 |
Affected packages |

Description |
| 41 |
=========== |
| 42 |
|
| 43 |
Gentoo packaging for OpenLDAP and Gauche may introduce insecure paths |
| 44 |
into the list of directories that are searched for libraries at |
| 45 |
runtime. |
| 46 |
|
| 47 |
Impact |
| 48 |
====== |
| 49 |
|
| 50 |
A local attacker, who is a member of the "portage" group, could create |
| 51 |
a malicious shared object in the Portage temporary build directory that |
| 52 |
would be loaded at runtime by a dependent binary, potentially resulting |
| 53 |
in privilege escalation. |
| 54 |
|
| 55 |
Workaround |
| 56 |
========== |
| 57 |
|
| 58 |
Only grant "portage" group rights to trusted users. |
| 59 |
|
| 60 |
Resolution |
| 61 |
========== |
| 62 |
|
| 63 |
All OpenLDAP users should upgrade to the latest version: |
| 64 |
|
| 65 |
# emerge --sync |
| 66 |
# emerge --ask --oneshot --verbose net-nds/openldap |
| 67 |
|
| 68 |
All Gauche users should upgrade to the latest version: |
| 69 |
|
| 70 |
# emerge --sync |
| 71 |
# emerge --ask --oneshot --verbose ">=dev-lang/gauche-0.8.6-r1" |
| 72 |
