CVE Reference:
CAN-2004-0691, CAN-2004-0692, CAN-2004-0693
(Links to External Site)
|
Date: Dec 29 2004
|
Impact:
Denial of service via network, Execution of arbitrary code via network, User access via network
|
Fix Available: Yes Vendor Confirmed: Yes
|
Version(s): 3.3.2
|
Description:
Several vulnerabilities were reported in Qt. A remote user can create a specially crafted image file that, when viewed by the target user, will execute arbitrary code.
It is reported that Chris Evans discovered a heap-based buffer overflow in the Qt library in the processing of 8-bit RLE encoded BMP files. A remote user can create a specially crafted BMP file that, when viewed by the target user, will execute arbitrary code on the target user's system.
It is also reported that the handlers for XPM, GIF, and JPEG image types are also vulnerable.
[Editor's note: It appears that these flaws are related to the recently reported libpng vulnerabilities. However, we are issuing a separate alert because, according to Mandrake, separate CVE numbers have been issued.]
|
Impact:
A remote user may be able to cause an affected application to crash or execute arbitrary code. The specific impact depends on the application using Qt.
|
Solution:
Conectiva has released a fix.

PACKAGE : qt3
SUMMARY : Fixes for image loader vulnerabilities
DATE : 2004-09-22 10:55:00
ID : CLA-2004:866
RELEVANT
RELEASES : 9, 10

DESCRIPTION
QT[1] is a cross-platform GUI toolkit mostly used by KDE.
Chris Evans found[2] a heap overflow vulnerability[3] in the QT
library when handling 8-bit RLE encoded BMP files. An attacker could
use this to compromise the account used to view the specially crafted
image. Further investigations found similar vulnerabilities in
XPM[4], GIF[5] and JPEG image handlers.
SOLUTION
It is recommended that all qt users upgrade their packages.
IMPORTANT: all applications linked against libqt must be restarted
after the upgrade in order to close the vulnerabilities.
