Synopsis |
17 |
======== |
18 |
|
19 |
The make_oidjoins_check script, part of the PostgreSQL package, is |
20 |
vulnerable to symlink attacks, potentially allowing a local user to |
21 |
overwrite arbitrary files with the rights of the user running the |
22 |
utility. |
23 |
|
24 |
Background |
25 |
========== |
26 |
|
27 |
PostgreSQL is an open source database based on the POSTGRES database |
28 |
management system. It includes several contributed scripts including |
29 |
the make_oidjoins_check script. |
30 |
|
31 |
Affected packages |
32 |
================= |
33 |
|
34 |
------------------------------------------------------------------- |
35 |
Package / Vulnerable / Unaffected |
36 |
------------------------------------------------------------------- |
37 |
1 dev-db/postgresql <= 7.4.5-r1 >= 7.4.5-r2 |
38 |
*>= 7.3.7-r2 |

Description |
41 |
=========== |
42 |
|
43 |
The make_oidjoins_check script insecurely creates temporary files in |
44 |
world-writeable directories with predictable names. |
45 |
|
46 |
Impact |
47 |
====== |
48 |
|
49 |
A local attacker could create symbolic links in the temporary files |
50 |
directory, pointing to a valid file somewhere on the filesystem. When |
51 |
make_oidjoins_check is called, this would result in file overwrite with |
52 |
the rights of the user running the utility, which could be the root |
53 |
user. |
54 |
|
55 |
Workaround |
56 |
========== |
57 |
|
58 |
There is no known workaround at this time. |
59 |
|
60 |
Resolution |
61 |
========== |
62 |
|
63 |
All PostgreSQL users should upgrade to the latest version: |
64 |
|
65 |
# emerge sync |
66 |
|
67 |
# emerge -pv ">=dev-db/postgresql-7.4.5-r2" |
68 |
# emerge ">=dev-db/postgresql-7.4.5-r2" |
69 |
|
70 |
Upgrade notes: PostgreSQL 7.3.x users should upgrade to the latest |
71 |
available 7.3.x version to retain database compatibility. |
