Synopsis |
16 |
======== |
17 |
|
18 |
Git contains multiple vulnerabilities that allow for the remote |
19 |
execution of arbitrary code. |
20 |
|
21 |
Background |
22 |
========== |
23 |
|
24 |
Git is a free and open source distributed version control system |
25 |
designed to handle everything from small to very large projects with |
26 |
speed and efficiency. |
27 |
|
28 |
Affected packages |
29 |
================= |
30 |
|
31 |
------------------------------------------------------------------- |
32 |
Package / Vulnerable / Unaffected |
33 |
------------------------------------------------------------------- |
34 |
1 dev-vcs/git < 2.7.3-r1 >= 2.7.3-r1 |
35 |
|
36 |
Description |
37 |
=========== |
38 |
|
39 |
Git is vulnerable to the remote execution of arbitrary code by cloning |
40 |
repositories with large filenames or a large number of nested trees. |
41 |
Additionally, some protocols within Git, such as git-remote-ext, can |
42 |
execute arbitrary code found within URLs. These URLs that submodules |
43 |
use may come from arbitrary sources (e.g., .gitmodules files in a |
44 |
remote repository), and can effect those who enable recursive fetch. |
45 |
Restrict the allowed protocols to well known and safe ones. |
46 |
|
47 |
Impact |
48 |
====== |
49 |
|
50 |
Remote attackers could execute arbitrary code on both client and |
51 |
server. |
52 |
|
53 |
Workaround |
54 |
========== |
55 |
|
56 |
There is no known workaround at this time. |
57 |
|
58 |
Resolution |
59 |
========== |
60 |
|
61 |
All Git users should upgrade to the latest version: |
62 |
|
63 |
# emerge --sync |
64 |
# emerge --ask --oneshot --verbose ">=dev-vcs/git-2.7.3-r1" |
65 |
|
