Synopsis |
| 16 |
======== |
| 17 |
|
| 18 |
PostgreSQL contains multiple vulnerabilities that could result in |
| 19 |
privilege escalation or a Denial of Service. |
| 20 |
|
| 21 |
Background |
| 22 |
========== |
| 23 |
|
| 24 |
PostgreSQL is an open source object-relational database management |
| 25 |
system. |
| 26 |
|
| 27 |
Affected packages |
| 28 |
================= |
| 29 |
|
| 30 |
------------------------------------------------------------------- |
| 31 |
Package / Vulnerable / Unaffected |
| 32 |
------------------------------------------------------------------- |
| 33 |
1 dev-db/postgresql < 8.0.15 >= 8.0.15 |
| 34 |
*>= 7.4.19 |
| 35 |
*>= 7.3.21 |

Description |
| 38 |
=========== |
| 39 |
|
| 40 |
If using the "expression indexes" feature, PostgreSQL executes index |
| 41 |
functions as the superuser during VACUUM and ANALYZE instead of the |
| 42 |
table owner, and allows SET ROLE and SET SESSION AUTHORIZATION in the |
| 43 |
index functions (CVE-2007-6600). Additionally, several errors involving |
| 44 |
regular expressions were found (CVE-2007-4769, CVE-2007-4772, |
| 45 |
CVE-2007-6067). Eventually, a privilege escalation vulnerability via |
| 46 |
unspecified vectors in the DBLink module was reported (CVE-2007-6601). |
| 47 |
This vulnerability is exploitable when local trust or ident |
| 48 |
authentication is used, and is due to an incomplete fix of |
| 49 |
CVE-2007-3278. |
| 50 |
|
| 51 |
Impact |
| 52 |
====== |
| 53 |
|
| 54 |
A remote authenticated attacker could send specially crafted queries |
| 55 |
containing complex regular expressions to the server that could result |
| 56 |
in a Denial of Service by a server crash (CVE-2007-4769), an infinite |
| 57 |
loop (CVE-2007-4772) or a memory exhaustion (CVE-2007-6067). The two |
| 58 |
other vulnerabilities can be exploited to gain additional privileges. |
| 59 |
|
| 60 |
Workaround |
| 61 |
========== |
| 62 |
|
| 63 |
There is no known workaround for all these issues at this time. |
| 64 |
|
| 65 |
Resolution |
| 66 |
========== |
| 67 |
|
| 68 |
All PostgreSQL users should upgrade to the latest version: |
| 69 |
|
| 70 |
# emerge --sync |
| 71 |
# emerge --ask --oneshot --verbose "dev-db/postgresql" |
| 72 |
|
