Synopsis |
| 16 |
======== |
| 17 |
|
| 18 |
A vulnerability in GNU TeXmacs could result in privilege escalation. |
| 19 |
|
| 20 |
Background |
| 21 |
========== |
| 22 |
|
| 23 |
GNU TeXmacs is a free WYSIWYG editing platform with special features |
| 24 |
for scientists. |
| 25 |
|
| 26 |
Affected packages |
| 27 |
================= |
| 28 |
|
| 29 |
------------------------------------------------------------------- |
| 30 |
Package / Vulnerable / Unaffected |
| 31 |
------------------------------------------------------------------- |
| 32 |
1 app-office/texmacs < 1.0.7.2-r1 >= 1.0.7.2-r1 |
| 33 |
|
| 34 |
Description |
| 35 |
=========== |
| 36 |
|
| 37 |
The texmacs and tm_mupad_help scripts in TeXmacs place a zero-length |
| 38 |
directory name in the LD_LIBRARY_PATH, which might result in the |
| 39 |
current working directory (.) to be included when searching for |
| 40 |
dynamically linked libraries. |
| 41 |
|
| 42 |
Impact |
| 43 |
====== |
| 44 |
|
| 45 |
A local attacker could gain escalated privileges via a specially |
| 46 |
crafted shared library. |
| 47 |
|
| 48 |
Workaround |
| 49 |
========== |
| 50 |
|
| 51 |
There is no known workaround at this time. |
| 52 |
|
| 53 |
Resolution |
| 54 |
========== |
| 55 |
|
| 56 |
All GNU TeXmacs users should upgrade to the latest version: |
| 57 |
|
| 58 |
# emerge --sync |
| 59 |
# emerge --ask --oneshot --verbose ">=app-office/texmacs-1.0.7.2-r1" |
| 60 |
|
