http://security.gentoo.org/

Severity:	normal
Title:	Qt: Untrusted library search path
Date:	03/01/2005
Bugs:	#75181
ID:	200503-01

Synopsis

Qt may load shared libraries from an untrusted, world-writable directory, resulting in the execution of arbitrary code.

Background

Qt is a cross-platform GUI toolkit used by KDE.

Affected packages

Package	Vulnerable	Unaffected	Architecture(s)
x11-libs/qt	< 3.3.4-r2	>= 3.3.4-r2	All supported architectures

Description

Tavis Ormandy of the Gentoo Linux Security Audit Team has discovered that Qt searches for shared libraries in an untrusted, world-writable directory.

Impact

A local attacker could create a malicious shared object that would be loaded by Qt, resulting in the execution of arbitrary code with the privileges of the Qt application.

Workaround

There is no known workaround at this time.

Resolution

All Qt users should upgrade to the latest version:

    # emerge --sync
    # emerge --ask --oneshot --verbose ">=x11-libs/qt-3.3.4-r2"
