Red Hat Security Advisory 2013-0669-01
Posted Mar 21, 2013
Authored by Red Hat | Site access.redhat.com

Red Hat Security Advisory 2013-0669-01 - Qt is a software toolkit that simplifies the task of writing and maintaining GUI applications for the X Window System. It was discovered that the QSharedMemory class implementation of the Qt toolkit created shared memory segments with insecure permissions. A local attacker could use this flaw to read or alter the contents of a particular shared memory segment, possibly leading to their ability to obtain sensitive information or influence the behavior of a process that is using the shared memory segment.

3. Description:

Qt is a software toolkit that simplifies the task of writing and
maintaining GUI (Graphical User Interface) applications for the X Window
System.

It was discovered that the QSharedMemory class implementation of the Qt
toolkit created shared memory segments with insecure permissions. A local
attacker could use this flaw to read or alter the contents of a particular
shared memory segment, possibly leading to their ability to obtain
sensitive information or influence the behavior of a process that is using
the shared memory segment. (CVE-2013-0254)

Red Hat would like to thank the Qt project for reporting this issue.
Upstream acknowledges Tim Brown and Mark Lowe of Portcullis Computer
Security Ltd. as the original reporters.

Users of Qt should upgrade to these updated packages, which contain a
backported patch to correct this issue. All running applications linked
against Qt libraries must be restarted for this update to take effect.

4. Solution:

Before applying this update, make sure all previously-released errata
relevant to your system have been applied.

This update is available via the Red Hat Network. Details on how to
use the Red Hat Network to apply this update are available at
https://access.redhat.com/knowledge/articles/11258

5. Bugs fixed (http://bugzilla.redhat.com/):

907425 - CVE-2013-0254 qt: QSharedMemory class created shared memory segments with insecure permissions
