Synopsis |
| 16 |
======== |
| 17 |
|
| 18 |
An information leak in mod_authz_svn could allow sensitive metadata of |
| 19 |
protected areas to be leaked to unauthorized users. |
| 20 |
|
| 21 |
Background |
| 22 |
========== |
| 23 |
|
| 24 |
Subversion is a versioning system designed to be a replacement for CVS. |
| 25 |
mod_authz_svn is an Apache module to do path-based authentication for |
| 26 |
Subversion repositories. |
| 27 |
|
| 28 |
Affected packages |
| 29 |
================= |

Package / Vulnerable / Unaffected |

Description |
| 37 |
=========== |
| 38 |
|
| 39 |
There is a bug in mod_authz_svn that causes it to reveal logged |
| 40 |
metadata regarding commits to protected areas. |
| 41 |
|
| 42 |
Impact |
| 43 |
====== |
| 44 |
|
| 45 |
Protected files themselves will not be revealed, but an attacker could |
| 46 |
use the metadata to reveal the existence of protected areas, such as |
| 47 |
paths, file versions, and the commit logs from those areas. |
| 48 |
|
| 49 |
Workaround |
| 50 |
========== |
| 51 |
|
| 52 |
Rather than using mod_authz_svn, move protected areas into seperate |
| 53 |
repositories and use native Apache authentication to make these |
| 54 |
repositories unreadable. |
| 55 |
|
| 56 |
Resolution |
| 57 |
========== |
| 58 |
|
| 59 |
All Subversion users should upgrade to the latest version: |
| 60 |
|
| 61 |
# emerge sync |
| 62 |
|
| 63 |
# emerge -pv ">=dev-util/subversion-1.0.8" |
| 64 |
# emerge ">=dev-util/subversion-1.0.8" |
| 65 |
|
