Synopsis |
16 |
======== |
17 |
|
18 |
A command injection vulnerability in Git may allow remote attackers to |
19 |
execute arbitrary code. |
20 |
|
21 |
Background |
22 |
========== |
23 |
|
24 |
Git is a small and fast distributed version control system designed to |
25 |
handle small and large projects. |
26 |
|
27 |
Affected packages |
28 |
================= |
29 |
|
30 |
------------------------------------------------------------------- |
31 |
Package / Vulnerable / Unaffected |
32 |
------------------------------------------------------------------- |
33 |
1 dev-vcs/git < 2.13.5 >= 2.13.5 |
34 |
|
35 |
Description |
36 |
=========== |
37 |
|
38 |
Specially crafted 'ssh://...' URLs may allow the owner of the |
39 |
repository to execute arbitrary commands on client's machine if those |
40 |
commands are already installed on the client's system. This is |
41 |
especially dangerous when the third-party repository has one or more |
42 |
submodules with specially crafted 'ssh://...' URLs. Each time the |
43 |
repository is recursively cloned or submodules are updated the payload |
44 |
will be triggered. |
45 |
|
46 |
Impact |
47 |
====== |
48 |
|
49 |
A remote attacker, by enticing a user to clone a specially crafted |
50 |
repository, could possibly execute arbitrary code with the privileges |
51 |
of the process. |
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-2.13.5" |
65 |
