Synopsis |
16 |
======== |
17 |
|
18 |
There is a vulnerability in the Subversion date parsing code which may |
19 |
lead to denial of service attacks, or execution of arbitrary code. |
20 |
Both the client and server are vulnerable. |
21 |
|
22 |
Background |
23 |
========== |
24 |
|
25 |
Subversion is a version control system intended to eventually replace |
26 |
CVS. Like CVS, it has an optional client-server architecture (where the |
27 |
server can be an Apache server running mod_svn, or an ssh program as in |
28 |
CVS's :ext: method). In addition to supporting the features found in |
29 |
CVS, Subversion also provides support for moving and copying files and |
30 |
directories. |

Description |
41 |
=========== |
42 |
|
43 |
All releases of Subversion prior to 1.0.3 have a vulnerability in the |
44 |
date-parsing code. This vulnerability may allow denial of service or |
45 |
arbitrary code execution as the Subversion user. Both the client and |
46 |
server are vulnerable, and write access is NOT required to the server's |
47 |
repository. |
48 |
|
49 |
Impact |
50 |
====== |
51 |
|
52 |
All servers and clients are vulnerable. Specifically, clients that |
53 |
allow other users to write to administrative files in a working copy |
54 |
may be exploited. Additionally all servers (whether they are httpd/DAV |
55 |
or svnserve) are vulnerable. Write access to the server is not |
56 |
required; public read-only Subversion servers are also exploitable. |
57 |
|
58 |
Workaround |
59 |
========== |
60 |
|
61 |
There is no known workaround at this time. All users are encouraged to |
62 |
upgrade to the latest available version. |
63 |
|
64 |
Resolution |
65 |
========== |
66 |
|
67 |
All Subversion users should upgrade to the latest stable version: |
68 |
|
69 |
# emerge sync |
70 |
|
71 |
# emerge -pv ">=dev-util/subversion-1.0.3" |
72 |
# emerge ">=dev-util/subversion-1.0.3" |
73 |
