Synopsis |
| 16 |
======== |
| 17 |
|
| 18 |
Several serious vulnerabilities have been found in CVS, which may allow |
| 19 |
an attacker to remotely compromise a CVS server or cause a DoS. |
| 20 |
|
| 21 |
Background |
| 22 |
========== |
| 23 |
|
| 24 |
CVS (Concurrent Versions System) is an open-source network-transparent |
| 25 |
version control system. It contains both a client utility and a server. |
| 26 |
|
| 27 |

Description |
| 36 |
=========== |
| 37 |
|
| 38 |
Alen Zukich has discovered several serious security issues in CVS, |
| 39 |
including at least one buffer overflow (CAN-2005-0753), memory leaks |
| 40 |
and a NULL pointer dereferencing error. |
| 41 |
|
| 42 |
Impact |
| 43 |
====== |
| 44 |
|
| 45 |
An attacker could exploit these vulnerabilities to cause a Denial of |
| 46 |
Service or execute arbitrary code with the permissions of the CVS |
| 47 |
pserver or the authenticated user (depending on the connection method |
| 48 |
used). |
| 49 |
|
| 50 |
Workaround |
| 51 |
========== |
| 52 |
|
| 53 |
There is no known workaround at this time. |
| 54 |
|
| 55 |
Resolution |
| 56 |
========== |
| 57 |
|
| 58 |
All CVS users should upgrade to the latest version: |
| 59 |
|
| 60 |
# emerge --sync |
| 61 |
# emerge --ask --oneshot --verbose ">=dev-util/cvs-1.11.18-r1" |
| 62 |
|
