Synopsis |
16 |
======== |
17 |
|
18 |
Multiple vulnerabilities have been discovered in the GNU debugger, |
19 |
potentially allowing the execution of arbitrary code. |
20 |
|
21 |
Background |
22 |
========== |
23 |
|
24 |
gdb is the GNU project's debugger, facilitating the analysis and |
25 |
debugging of applications. The BFD library provides a uniform method of |
26 |
accessing a variety of object file formats. |
27 |
|
28 |
Affected packages |
29 |
================= |
30 |
|
31 |
------------------------------------------------------------------- |
32 |
Package / Vulnerable / Unaffected |
33 |
------------------------------------------------------------------- |
34 |
1 sys-devel/gdb < 6.3-r3 >= 6.3-r3 |

Description |
37 |
=========== |
38 |
|
39 |
Tavis Ormandy of the Gentoo Linux Security Audit Team discovered an |
40 |
integer overflow in the BFD library, resulting in a heap overflow. A |
41 |
review also showed that by default, gdb insecurely sources |
42 |
initialisation files from the working directory. |
43 |
|
44 |
Impact |
45 |
====== |
46 |
|
47 |
Successful exploitation would result in the execution of arbitrary code |
48 |
on loading a specially crafted object file or the execution of |
49 |
arbitrary commands. |
50 |
|
51 |
Workaround |
52 |
========== |
53 |
|
54 |
There is no known workaround at this time. |
55 |
|
56 |
Resolution |
57 |
========== |
58 |
|
59 |
All gdb users should upgrade to the latest stable version: |
60 |
|
61 |
# emerge --sync |
62 |
# emerge --ask --oneshot --verbose ">=sys-devel/gdb-6.3-r3" |
63 |
