Synopsis |
17 |
======== |
18 |
|
19 |
There are two vulnerabilities in CVS; one in the server and one in the |
20 |
client. These vulnerabilities allow the reading and writing of |
21 |
arbitrary files on both client and server. |
22 |
|
23 |
Background |
24 |
========== |
25 |
|
26 |
CVS, which stands for Concurrent Versions System, is a client/server |
27 |
application which tracks changes to sets of files. It allows multiple |
28 |
users to work concurrently on files, and then merge their changes back |
29 |
into the main tree (which can be on a remote system). It also allows |
30 |
branching, or maintaining separate versions for files. |

Description |
41 |
=========== |
42 |
|
43 |
There are two vulnerabilities in CVS; one in the server and one in the |
44 |
client. The server vulnerability allows a malicious client to request |
45 |
the contents of any RCS file to which the server has permission, even |
46 |
those not located under $CVSROOT. The client vulnerability allows a |
47 |
malicious server to overwrite files on the client machine anywhere the |
48 |
client has permissions. |
49 |
|
50 |
Impact |
51 |
====== |
52 |
|
53 |
Arbitrary files may be read or written on CVS clients and servers by |
54 |
anybody with access to the CVS tree. |
55 |
|
56 |
Workaround |
57 |
========== |
58 |
|
59 |
There is no known workaround at this time. All users are encouraged to |
60 |
upgrade to the latest stable version of CVS. |
61 |
|
62 |
Resolution |
63 |
========== |
64 |
|
65 |
All CVS users should upgrade to the latest stable version. |
