15 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
35
36 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"
