Synopsis |
| 16 |
======== |
| 17 |
|
| 18 |
PostgreSQL is vulnerable to Denial of Service attacks and possibly |
| 19 |
allows unprivileged users to gain administrator rights. |
| 20 |
|
| 21 |
Background |
| 22 |
========== |
| 23 |
|
| 24 |
PostgreSQL is a SQL compliant, open source object-relational database |
| 25 |
management system. |
| 26 |
|
| 27 |
Affected packages |

Description |
| 38 |
=========== |
| 39 |
|
| 40 |
PostgreSQL gives public EXECUTE access to a number of character |
| 41 |
conversion routines, but doesn't validate the given arguments |
| 42 |
(CAN-2005-1409). It has also been reported that the contrib/tsearch2 |
| 43 |
module of PostgreSQL misdeclares the return value of some functions as |
| 44 |
"internal" (CAN-2005-1410). |
| 45 |
|
| 46 |
Impact |
| 47 |
====== |
| 48 |
|
| 49 |
An attacker could call the character conversion routines with specially |
| 50 |
setup arguments to crash the backend process of PostgreSQL or to |
| 51 |
potentially gain administrator rights. A malicious user could also call |
| 52 |
the misdeclared functions of the contrib/tsearch2 module, resulting in |
| 53 |
a Denial of Service or other, yet uninvestigated, impacts. |
| 54 |
|
| 55 |
Workaround |
| 56 |
========== |
| 57 |
|
| 58 |
There is no known workaround at this time. |
| 59 |
|
| 60 |
Resolution |
| 61 |
========== |
| 62 |
|
| 63 |
All PostgreSQL users should update to the latest available version and |
| 64 |
follow the guide at http://www.postgresql.org/about/news.315 |
| 65 |
|
| 66 |
# emerge --sync |
| 67 |
# emerge --ask --oneshot --verbose dev-db/postgresql |
