Synopsis |
| 19 |
======== |
| 20 |
|
| 21 |
Multiple vulnerabilities were discovered in CSTeX, possibly allowing to |
| 22 |
execute arbitrary code or overwrite arbitrary files. |
| 23 |
|
| 24 |
Background |
| 25 |
========== |
| 26 |
|
| 27 |
CSTeX is a TeX distribution with Czech and Slovak support. It is used |
| 28 |
for creating and manipulating LaTeX documents. |
| 29 |
|
| 30 |
Affected packages |
| 31 |
================= |
| 32 |
|
| 33 |
------------------------------------------------------------------- |
| 34 |
Package / Vulnerable / Unaffected |
| 35 |
------------------------------------------------------------------- |
| 36 |
1 app-text/cstetex < 2.0.2-r2 Vulnerable! |
| 37 |
------------------------------------------------------------------- |
| 38 |
NOTE: Certain packages are still vulnerable. Users should migrate |
| 39 |
to another package if one is available or wait for the |
| 40 |
existing packages to be marked stable by their |
| 41 |
architecture maintainers. |
| 42 |

Description |
| 47 |
=========== |
| 48 |
|
| 49 |
Multiple issues were found in the teTeX 2 codebase that CSTeX builds |
| 50 |
upon (GLSA 200709-17, GLSA 200711-26). CSTeX also includes vulnerable |
| 51 |
code from the GD library (GLSA 200708-05), from Xpdf (GLSA 200709-12, |
| 52 |
GLSA 200711-22) and from T1Lib (GLSA 200710-12). |
| 53 |
|
| 54 |
Impact |
| 55 |
====== |
| 56 |
|
| 57 |
Remote attackers could possibly execute arbitrary code and local |
| 58 |
attackers could possibly overwrite arbitrary files with the privileges |
| 59 |
of the user running CSTeX via multiple vectors. |
| 60 |
|
| 61 |
Workaround |
| 62 |
========== |
| 63 |
|
| 64 |
There is no known workaround at this time. |
| 65 |
|
| 66 |
Resolution |
| 67 |
========== |
| 68 |
|
| 69 |
CSTeX is not maintained upstream, so the package was masked in Portage. |
| 70 |
We recommend that users unmerge CSTeX: |
| 71 |
|
| 72 |
# emerge --unmerge app-text/cstetex |
| 73 |
|
| 74 |
As an alternative, users should upgrade their systems to use teTeX or |
| 75 |
TeX Live with its Babel packages. |
| 76 |
