Synopsis |
| 16 |
======== |
| 17 |
|
| 18 |
Multiple integer overflows, leading to heap-based buffer overflows in |
| 19 |
the Subversion client and server might allow remote attackers to |
| 20 |
execute arbitrary code. |
| 21 |
|
| 22 |
Background |
| 23 |
========== |
| 24 |
|
| 25 |
Subversion is a versioning system designed to be a replacement for CVS. |
| 26 |
|
| 27 |
Affected packages |
| 28 |
================= |
| 29 |
|
| 30 |
------------------------------------------------------------------- |
| 31 |
Package / Vulnerable / Unaffected |
| 32 |
------------------------------------------------------------------- |
| 33 |
1 dev-util/subversion < 1.6.4 >= 1.6.4 |
| 34 |
|
| 35 |
Description |
| 36 |
=========== |
| 37 |
|
| 38 |
Matt Lewis of Google reported multiple integer overflows in the |
| 39 |
libsvn_delta library, possibly leading to heap-based buffer overflows. |
| 40 |
|
| 41 |
Impact |
| 42 |
====== |
| 43 |
|
| 44 |
A remote attacker with commit access could exploit this vulnerability |
| 45 |
by sending a specially crafted commit to a Subversion server, or a |
| 46 |
remote attacker could entice a user to check out or update a repository |
| 47 |
from a malicious Subversion server, possibly resulting in the execution |
| 48 |
of arbitrary code with the privileges of the user running the server or |
| 49 |
client. |
| 50 |
|
| 51 |
Workaround |
| 52 |
========== |
| 53 |
|
| 54 |
There is no known workaround at this time. |
| 55 |
|
| 56 |
Resolution |
| 57 |
========== |
| 58 |
|
| 59 |
All Subversion users should upgrade to the latest version: |
| 60 |
|
| 61 |
# emerge --sync |
| 62 |
# emerge --ask --oneshot --verbose =dev-util/subversion-1.6.4 |
| 63 |
