Synopsis |
| 16 |
======== |
| 17 |
|
| 18 |
Multiple packages suffer from RUNPATH issues that may allow users in |
| 19 |
the "portage" group to escalate privileges. |
| 20 |
|
| 21 |
Background |
| 22 |
========== |
| 23 |
|
| 24 |
Perl is a stable, cross-platform programming language created by Larry |
| 25 |
Wall. Qt-UnixODBC is an ODBC library for Qt. CMake is a cross-platform |
| 26 |
build environment. |
| 27 |
|
| 28 |

Description |
| 44 |
=========== |
| 45 |
|
| 46 |
Some packages may introduce insecure paths into the list of directories |
| 47 |
that are searched for libraries at runtime. Furthermore, packages |
| 48 |
depending on the MakeMaker Perl module for build configuration may have |
| 49 |
incorrectly copied the LD_RUN_PATH into the DT_RPATH. |
| 50 |
|
| 51 |
Impact |
| 52 |
====== |
| 53 |
|
| 54 |
A local attacker, who is a member of the "portage" group, could create |
| 55 |
a malicious shared object in the Portage temporary build directory that |
| 56 |
would be loaded at runtime by a dependent executable, potentially |
| 57 |
resulting in privilege escalation. |
| 58 |
|
| 59 |
Workaround |
| 60 |
========== |
| 61 |
|
| 62 |
Only grant "portage" group rights to trusted users. |
| 63 |
|
| 64 |
Resolution |
| 65 |
========== |
| 66 |
|
| 67 |
All Perl users should upgrade to the latest version: |
| 68 |
|
| 69 |
# emerge --sync |
| 70 |
# emerge --ask --oneshot --verbose dev-lang/perl |
| 71 |
|
| 72 |
All Qt-UnixODBC users should upgrade to the latest version: |
| 73 |
|
| 74 |
# emerge --sync |
| 75 |
# emerge --ask --oneshot --verbose ">=dev-db/qt-unixodbc-3.3.4-r1" |
| 76 |
|
| 77 |
All CMake users should upgrade to the latest version: |
| 78 |
|
| 79 |
# emerge --sync |
| 80 |
# emerge --ask --oneshot --verbose dev-util/cmake |
| 81 |
|
