Synopsis |
| 19 |
======== |
| 20 |
|
| 21 |
Multiple insecure temporary file vulnerabilities have been discovered |
| 22 |
in the Website META Language. |
| 23 |
|
| 24 |
Background |
| 25 |
========== |
| 26 |
|
| 27 |
Website META Language is a free and extensible Webdesigner's off-line |
| 28 |
HTML generation toolkit for Unix. |
| 29 |
|
| 30 |
Affected packages |
| 31 |
================= |
| 32 |
|
| 33 |
------------------------------------------------------------------- |
| 34 |
Package / Vulnerable / Unaffected |
| 35 |
------------------------------------------------------------------- |
| 36 |
1 dev-lang/wml < 2.0.11-r3 >= 2.0.11-r3 |
| 37 |
|
| 38 |
Description |
| 39 |
=========== |
| 40 |
|
| 41 |
Temporary files are handled insecurely in the files |
| 42 |
wml_backend/p1_ipp/ipp.src, wml_contrib/wmg.cgi, and |
| 43 |
wml_backend/p3_eperl/eperl_sys.c, allowing users to overwrite or delete |
| 44 |
arbitrary files with the privileges of the user running the program. |
| 45 |
|
| 46 |
Impact |
| 47 |
====== |
| 48 |
|
| 49 |
Local users can exploit the insecure temporary file vulnerabilities via |
| 50 |
symlink attacks to perform certain actions with escalated privileges. |
| 51 |
|
| 52 |
Workaround |
| 53 |
========== |
| 54 |
|
| 55 |
Restrict access to the temporary directory to trusted users only. |
| 56 |
|
| 57 |
Resolution |
| 58 |
========== |
| 59 |
|
| 60 |
All Website META Language users should upgrade to the latest version: |
| 61 |
|
| 62 |
# emerge --sync |
| 63 |
# emerge --ask --oneshot --verbose ">=dev-lang/wml-2.0.11-r3" |
| 64 |
