Synopsis |
| 16 |
======== |
| 17 |
|
| 18 |
The gettext utility is vulnerable to symlink attacks, potentially |
| 19 |
allowing a local user to overwrite or change permissions on arbitrary |
| 20 |
files with the rights of the user running gettext, which could be the |
| 21 |
root user. |
| 22 |
|
| 23 |
Background |
| 24 |
========== |
| 25 |
|
| 26 |
gettext is a set of utilities for the GNU Translation Project which |
| 27 |
provides a set of tools and documentation to help produce multi-lingual |
| 28 |
messages in programs. |
| 29 |
|
| 30 |
Affected packages |
| 31 |
================= |
| 32 |
|
| 33 |
------------------------------------------------------------------- |
| 34 |
Package / Vulnerable / Unaffected |
| 35 |
------------------------------------------------------------------- |
| 36 |
1 sys-devel/gettext < 0.12.1-r2 >= 0.12.1-r2 |
| 37 |
|
| 38 |
Description |
| 39 |
=========== |
| 40 |
|
| 41 |
gettext insecurely creates temporary files in world-writeable |
| 42 |
directories with predictable names. |
| 43 |
|
| 44 |
Impact |
| 45 |
====== |
| 46 |
|
| 47 |
A local attacker could create symbolic links in the temporary files |
| 48 |
directory, pointing to a valid file somewhere on the filesystem. When |
| 49 |
gettext is called, this would result in file access with the rights of |
| 50 |
the user running the utility, which could be the root user. |
| 51 |
|
| 52 |
Workaround |
| 53 |
========== |
| 54 |
|
| 55 |
There is no known workaround at this time. |
| 56 |
|
| 57 |
Resolution |
| 58 |
========== |
| 59 |
|
| 60 |
All gettext users should upgrade to the latest version: |
| 61 |
|
| 62 |
# emerge sync |
| 63 |
|
| 64 |
# emerge -pv ">=sys-devel/gettext-0.12.1-r2" |
| 65 |
# emerge ">=sys-devel/gettext-0.12.1.-r2" |
| 66 |
