Synopsis |
| 16 |
======== |
| 17 |
|
| 18 |
Multiple heap-based buffer overflows in E2fsprogs could result in the |
| 19 |
execution of arbitrary code. |
| 20 |
|
| 21 |
Background |
| 22 |
========== |
| 23 |
|
| 24 |
E2fsprogs provides utilities for use with the ext2 and ext3 file |
| 25 |
systems including the libext2fs library that allows user-level programs |
| 26 |
to manipulate an ext2 or ext3 file system. |
| 27 |
|
| 28 |
Affected packages |
| 29 |
================= |
| 30 |
|

------------------------------------------------------------------- |
| 32 |
Package / Vulnerable / Unaffected |
| 33 |

Description |
| 37 |
=========== |
| 38 |
|
| 39 |
Rafal Wojtczuk (McAfee AVERT Research) discovered multiple integer |
| 40 |
overflows in libext2fs, that are triggered when processing information |
| 41 |
from within the file system, resulting in heap-based buffer overflows. |
| 42 |
|
| 43 |
Impact |
| 44 |
====== |
| 45 |
|
| 46 |
An attacker could entice a user to process a specially-crafted ext2 or |
| 47 |
ext3 file system image (with tools linking against libext2fs, e.g. |
| 48 |
fsck, forensic tools or Xen's pygrub), possibly resulting in the |
| 49 |
execution of arbitrary code with the privileges of the user running the |
| 50 |
application. |
| 51 |
|
| 52 |
Workaround |
| 53 |
========== |
| 54 |
|
| 55 |
There is no known workaround at this time. |
| 56 |
|
| 57 |
Resolution |
| 58 |
========== |
| 59 |
|
| 60 |
All E2fsprogs users should upgrade to the latest version: |
| 61 |
|
| 62 |
# emerge --sync |
| 63 |
# emerge --ask --oneshot --verbose ">=sys-fs/e2fsprogs-1.40.3" |
| 64 |
|
