Synopsis |
| 16 |
======== |
| 17 |
|
| 18 |
Multiple insecure temporary file usage issues have been reported in |
| 19 |
LMBench, allowing for symlink attacks. |
| 20 |
|
| 21 |
Background |
| 22 |
========== |
| 23 |
|
| 24 |
LMBench is a suite of simple, portable benchmarks for UNIX platforms. |
| 25 |
|
| 26 |
Affected packages |
| 27 |
================= |
| 28 |
|
| 29 |
------------------------------------------------------------------- |
| 30 |
Package / Vulnerable / Unaffected |
| 31 |
------------------------------------------------------------------- |
| 32 |
1 app-benchmarks/lmbench <= 3 Vulnerable! |
| 33 |
------------------------------------------------------------------- |
| 34 |
NOTE: Certain packages are still vulnerable. Users should migrate |
| 35 |
to another package if one is available or wait for the |
| 36 |
existing packages to be marked stable by their |
| 37 |
architecture maintainers. |
| 38 |
|
| 39 |
Description |
| 40 |
=========== |
| 41 |
|
| 42 |
Dmitry E. Oboukhov reported that the rccs and STUFF scripts do not |
| 43 |
handle "/tmp/sdiff.#####" temporary files securely. NOTE: There might |
| 44 |
be further occurances of insecure temporary file usage. |
| 45 |
|
| 46 |
Impact |
| 47 |
====== |
| 48 |
|
| 49 |
A local attacker could perform symlink attacks to overwrite arbitrary |
| 50 |
files with the privileges of the user running the application. |
| 51 |
|
| 52 |
Workaround |
| 53 |
========== |
| 54 |
|
| 55 |
There is no known workaround at this time. |
| 56 |
|
| 57 |
Resolution |
| 58 |
========== |
| 59 |
|
| 60 |
LMBench has been removed from Portage. We recommend that users unmerge |
| 61 |
LMBench: |
| 62 |
|
| 63 |
# emerge --unmerge app-benchmarks/lmbench |
| 64 |
|
