Synopsis |
| 16 |
======== |
| 17 |
|
| 18 |
A buffer overflow in LibAST may result in execution of arbitrary code |
| 19 |
with escalated privileges. |
| 20 |
|
| 21 |
Background |
| 22 |
========== |
| 23 |
|
| 24 |
LibAST is a utility library that was originally intended to accompany |
| 25 |
Eterm, but may be used by various other applications. |

Description |
| 36 |
=========== |
| 37 |
|
| 38 |
Michael Jennings discovered an exploitable buffer overflow in the |
| 39 |
configuration engine of LibAST. |
| 40 |
|
| 41 |
Impact |
| 42 |
====== |
| 43 |
|
| 44 |
The vulnerability can be exploited to gain escalated privileges if the |
| 45 |
application using LibAST is setuid/setgid and passes a specifically |
| 46 |
crafted filename to LibAST's configuration engine. |
| 47 |
|
| 48 |
Workaround |
| 49 |
========== |
| 50 |
|
| 51 |
Identify all applications linking against LibAST and verify they are |
| 52 |
not setuid/setgid. |
| 53 |
|
| 54 |
Resolution |
| 55 |
========== |
| 56 |
|
| 57 |
All users should upgrade to the latest version and run revdep-rebuild: |
| 58 |
|
| 59 |
# emerge --sync |
| 60 |
# emerge --ask --oneshot --verbose >=x11-libs/libast-0.7 |
| 61 |
# revdep-rebuild |
| 62 |
