Synopsis |
| 16 |
======== |
| 17 |
|
| 18 |
Multiple vulnerabilities in MySQL might lead to privilege escalation |
| 19 |
and Denial of Service. |
| 20 |
|
| 21 |
Background |
| 22 |
========== |
| 23 |
|
| 24 |
MySQL is a popular multi-threaded, multi-user SQL server. |
| 25 |
|
| 26 |
Affected packages |
| 27 |
================= |
| 28 |
|
| 29 |
------------------------------------------------------------------- |
| 30 |
Package / Vulnerable / Unaffected |
| 31 |

|
| 34 |
Description |
| 35 |
=========== |
| 36 |
|
| 37 |
Multiple vulnerabilities have been reported in MySQL: |
| 38 |
|
| 39 |
* Mattias Jonsson reported that a "RENAME TABLE" command against a |
| 40 |
table with explicit "DATA DIRECTORY" and "INDEX DIRECTORY" options |
| 41 |
would overwrite the file to which the symlink points (CVE-2007-5969). |
| 42 |
|
| 43 |
* Martin Friebe discovered that MySQL does not update the DEFINER |
| 44 |
value of a view when the view is altered (CVE-2007-6303). |
| 45 |
|
| 46 |
* Philip Stoev discovered that the federated engine expects the |
| 47 |
response of a remote MySQL server to contain a minimum number of |
| 48 |
columns in query replies (CVE-2007-6304). |
| 49 |
|
| 50 |
Impact |
| 51 |
====== |
| 52 |
|
| 53 |
An authenticated remote attacker could exploit the first vulnerability |
| 54 |
to overwrite MySQL system tables and escalate privileges, or use the |
| 55 |
second vulnerability to gain privileges via an "ALTER VIEW" statement. |
| 56 |
Remote federated MySQL servers could cause a Denial of Service in the |
| 57 |
local MySQL server by exploiting the third vulnerability. |
| 58 |
|
| 59 |
Workaround |
| 60 |
========== |
| 61 |
|
| 62 |
There is no known workaround at this time. |
| 63 |
|
| 64 |
Resolution |
| 65 |
========== |
| 66 |
|
| 67 |
All MySQL users should upgrade to the latest version: |
| 68 |
|
| 69 |
# emerge --sync |
| 70 |
# emerge --ask --oneshot --verbose ">=dev-db/mysql-5.0.54" |
| 71 |
|
