Synopsis |
| 19 |
======== |
| 20 |
|
| 21 |
A buffer overflow via environmental variables in Firebird may allow a |
| 22 |
local user to manipulate or destroy local databases and trojan the |
| 23 |
Firebird binaries. |
| 24 |
|
| 25 |
Background |
| 26 |
========== |
| 27 |
|
| 28 |
Firebird is an open source relational database that runs on Linux, |
| 29 |
Windows, and various UNIX systems. |
| 30 |
|
| 31 |
Affected packages |
| 32 |
================= |
| 33 |
|
| 34 |
------------------------------------------------------------------- |
| 35 |
Package / Vulnerable / Unaffected |
| 36 |
------------------------------------------------------------------- |
| 37 |
1 dev-db/firebird < 1.5 >= 1.5 |
| 38 |
|
| 39 |
Description |
| 40 |
=========== |
| 41 |
|
| 42 |
A buffer overflow exists in three Firebird binaries (gds_inet_server, |
| 43 |
gds_lock_mgr, and gds_drop) that is exploitable by setting a large |
| 44 |
value to the INTERBASE environment variable. |
| 45 |
|
| 46 |
Impact |
| 47 |
====== |
| 48 |
|
| 49 |
An attacker could control program execution, allowing privilege |
| 50 |
escalation to the UID of Firebird, full access to Firebird databases, |
| 51 |
and trojaning the Firebird binaries. An attacker could use this to |
| 52 |
compromise other user or root accounts. |
| 53 |
|
| 54 |
Workaround |
| 55 |
========== |
| 56 |
|
| 57 |
There is no known workaround. |
| 58 |
|
| 59 |
Resolution |
| 60 |
========== |
| 61 |
|
| 62 |
All users should upgrade to the latest version of Firebird: |
| 63 |
|
| 64 |
# emerge sync |
| 65 |
|
| 66 |
# emerge -pv ">=dev-db/firebird-1.5" |
| 67 |
# emerge ">=dev-db/firebird-1.5" |
| 68 |
|
