Synopsis |
16 |
======== |
17 |
|
18 |
Various utilities from the GNU Binutils and elfutils packages are |
19 |
vulnerable to a heap based buffer overflow, potentially resulting in |
20 |
the execution of arbitrary code. |
21 |
|
22 |
Background |
23 |
========== |
24 |
|
25 |
The GNU Binutils are a collection of tools to create, modify and |
26 |
analyse binary files. Many of the files use BFD, the Binary File |
27 |
Descriptor library, to do low-level manipulation. Elfutils provides a |
28 |
library and utilities to access, modify and analyse ELF objects. |

Description |
48 |
=========== |
49 |
|
50 |
Tavis Ormandy and Ned Ludd of the Gentoo Linux Security Audit Team |
51 |
discovered an integer overflow in the BFD library and elfutils, |
52 |
resulting in a heap based buffer overflow. |
53 |
|
54 |
Impact |
55 |
====== |
56 |
|
57 |
Successful exploitation would require a user to access a specially |
58 |
crafted binary file, resulting in the execution of arbitrary code. |
59 |
|
60 |
Workaround |
61 |
========== |
62 |
|
63 |
There is no known workaround at this time. |
64 |
|
65 |
Resolution |
66 |
========== |
67 |
|
68 |
All GNU Binutils users should upgrade to the latest version: |
69 |
|
70 |
# emerge --sync |
71 |
# emerge --ask --oneshot --verbose sys-devel/binutils |
72 |
|
73 |
All elfutils users should upgrade to the latest version: |
74 |
|
75 |
# emerge --sync |
76 |
# emerge --ask --oneshot --verbose ">=dev-libs/elfutils-0.108" |
77 |
