File 0004-QStandardPaths-Unix-improve-the-XDG_RUNTIME_DIR-crea.patch of Package libqt5-qtbase.18762
From ad3a75adc4c6197c3ce12aa30a897b2766761236 Mon Sep 17 00:00:00 2001 From: Thiago Macieira <thiago.macieira@intel.com> Date: Thu, 23 Jul 2020 18:17:19 -0700 Subject: [PATCH 4/4] QStandardPaths/Unix: improve the XDG_RUNTIME_DIR creation/detection First, use QT_MKDIR instead of QFileSystemEngine::createDirectory(), as the latter can't create a directory with the right permissions. That would allow an attacker to briefly obtain access to the runtime dir between the mkdir() and chmod() system calls. Second, make sure that if the target already exists that it is a directory and not a symlink (even to a directory). If it is a symlink that belongs to another user, it can be changed to point to another place, which we won't like. And as a bonus, we're printing more information to the user in case something went wrong. Sample outputs: QStandardPaths: runtime directory '/root' is not owned by UID 1000, but a directory permissions 0700 owned by UID 0 GID 0 QStandardPaths: runtime directory '/dev/null' is not a directory, but a character device, socket or FIFO permissions 0666 owned by UID 0 GID 0 QStandardPaths: runtime directory '/etc/passwd' is not a directory, but a regular file permissions 0644 owned by UID 0 GID 0 QStandardPaths: XDG_RUNTIME_DIR not set, defaulting to '/tmp/runtime-tjmaciei' QStandardPaths: runtime directory '/tmp/runtime-tjmaciei' is not a directory, but a symbolic link to a directory permissions 0755 owned by UID 1000 GID 100 Change-Id: Iea47e0f8fc8b40378df7fffd16248b663794c613 Reviewed-by: David Faure <david.faure@kdab.com> (cherry picked from commit ad5a65b6a2bfca1658634e380559d14ea1e904a4) Reviewed-by: Volker Hilsheimer <volker.hilsheimer@qt.io> (cherry picked from commit 99280f4ee9ad03412578147d0da0c6630ecc324c) --- src/corelib/io/qstandardpaths_unix.cpp | 163 +++++++---- .../io/qstandardpaths/qstandardpaths.pro | 2 - .../io/qstandardpaths/tst_qstandardpaths.cpp | 260 ++++++++++++++---- 3 files changed, 320 insertions(+), 105 deletions(-) diff --git a/src/corelib/io/qstandardpaths_unix.cpp b/src/corelib/io/qstandardpaths_unix.cpp index 8f87ecb97f..2c2aa07c46 100644 --- a/src/corelib/io/qstandardpaths_unix.cpp +++ b/src/corelib/io/qstandardpaths_unix.cpp @@ -1,6 +1,7 @@ /**************************************************************************** ** -** Copyright (C) 2016 The Qt Company Ltd. +** Copyright (C) 2020 The Qt Company Ltd. +** Copyright (C) 2020 Intel Corporation. ** Contact: https://www.qt.io/licensing/ ** ** This file is part of the QtCore module of the Qt Toolkit. @@ -68,6 +69,111 @@ static void appendOrganizationAndApp(QString &path) #endif } +static bool checkXdgRuntimeDir(const QString &xdgRuntimeDir) +{ + auto describeMetaData = [](const QFileSystemMetaData &metaData) -> QByteArray { + if (!metaData.exists()) + return "a broken symlink";
