Synopsis |
| 16 |
======== |
| 17 |
|
| 18 |
An off-by-one vulnerability has been discovered in Qt, possibly |
| 19 |
resulting in the execution of arbitrary code. |
| 20 |
|
| 21 |
Background |
| 22 |
========== |
| 23 |
|
| 24 |
Qt is a cross-platform GUI framework, which is used e.g. by KDE. |
| 25 |
|
| 26 |
Affected packages |
| 27 |
================= |
| 28 |
|
| 29 |
------------------------------------------------------------------- |
| 30 |
Package / Vulnerable / Unaffected |
| 31 |
------------------------------------------------------------------- |
| 32 |
1 x11-libs/qt < 3.3.8-r4 >= 3.3.8-r4 |
| 33 |
|
| 34 |
Description |
| 35 |
=========== |
| 36 |
|
| 37 |
Dirk Mueller from the KDE development team discovered a boundary error |
| 38 |
in file qutfcodec.cpp when processing Unicode strings. |
| 39 |
|
| 40 |
Impact |
| 41 |
====== |
| 42 |
|
| 43 |
A remote attacker could send a specially crafted Unicode string to a |
| 44 |
vulnerable Qt application, possibly resulting in the remote execution |
| 45 |
of arbitrary code with the privileges of the user running the |
| 46 |
application. Note that the boundary error is present but reported to be |
| 47 |
not exploitable in 4.x series. |
| 48 |
|
| 49 |
Workaround |
| 50 |
========== |
| 51 |
|
| 52 |
There is no known workaround at this time. |
| 53 |
|
| 54 |
Resolution |
| 55 |
========== |
| 56 |
|
| 57 |
All Qt 3.x users should upgrade to the latest version: |
| 58 |
|
| 59 |
# emerge --sync |
| 60 |
# emerge --ask --oneshot --verbose ">=x11-libs/qt-3.3.8-r4" |
| 61 |
|
