Security announcement - Qt Creator 2.0.0 for desktop platforms

A vulnerability has been found in Qt Creator 2.0.0 and previous versions. The vulnerability occurs because of an insecure manipulation of a Unix environment variable by the "qtcreator" shell script. It manifests by causing Qt or Qt Creator to attempt to load certain library names from the current working directory.

This could cause certain Unix shared libraries to be loaded by Qt Creator from the current working directory. The issue does not affect Windows or Mac OS X. It also does not affect the most recent Qt Creator 2.0.1 release.

The issue has been assigned the identifier CVE-2010-3374. See http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2010-337

Recommendation

To nullify any risk posed by this issue, we recommend users of Qt Creator 2.0.0 or earlier upgrade to the most recent release, Qt 2.0.1. It can be downloaded from get.qt.nokhttp://www.blogger.com/img/blank.gifia.com

Users unable to upgrade at this time can replace their "qtcreator" scripts

with the qtcreator.bin binary found in the package distribution, or with the updated script found in the public Qt Creator repository.

The link to the updated script is: http://www.qt.gitorious.org/qt-creator/qt-creator/blobs/3c00715c8e90c57953ec4a8716110f6954e524e4/bin/qtcreator

Qt: Locale not supported on X server

After installed new Nokia Qt SDK 1.0.1/Qt 4.7.0 on Ubuntu 10.04, I tried to run my first application on emulator. The error message "Qt: Locale not supported on X server" was shown on Application Output.

As my understanding, it's because the X server cannot understand the language of the locale setting; depends on what the default LANG setting. It can be ignored, English will be used as locale language.

If you really want to remove the error message, you can change your locale setting:

edit file /etc/default/locale with root's right

$sudo gedit locale

replace the LANG setting with:

LANG="en_US.UTF8"

And re-start your system to make it take effect.
