CVE-2015-1858

Updated qt3, qt4, and qtbase5 packages fix security vulnerabilities:

It is possible to construct invalid BMP (CVE-2015-1858), ICO (CVE-2015-1859) and GIF (CVE-2015-1860) images that lead to buffer overflows.

Qt3 is only vulnerable to the CVE-2015-1860 issue with GIF images.

These are all security issues fixed in the libqt4-32bit-4.8.7-5.4 package on the GA media of openSUSE Tumbleweed.

The libqt4 library was updated to fix several security issues:

* CVE-2015-0295: Division by zero when processing malformed BMP files.
  (bsc#921999)
* CVE-2015-1858: Segmentation fault in BMP Qt Image Format Handling.
  (bsc#927806)
* CVE-2015-1859: Segmentation fault in ICO Qt Image Format Handling.
  (bsc#927807)
* CVE-2015-1860: Segmentation fault in GIF Qt Image Format Handling.
  (bsc#927808)

The libqt4 library was updated to fix several security and non security issues.

The following vulnerabilities were fixed:

• bsc#921999: CVE-2015-0295: division by zero when processing malformed BMP files
• bsc#927806: CVE-2015-1858: segmentation fault in BMP Qt Image Format Handling
• bsc#927807: CVE-2015-1859: segmentation fault in ICO Qt Image Format Handling
• bsc#927808: CVE-2015-1860: segmentation fault in GIF Qt Image Format Handling

The following non-secuirty issues were fixed:

• bsc#929688: Critical Problem in Qt Network Stack
• bsc#847880: kde/qt rendering error in qemu cirrus i586
• Update use-freetype-default.diff to use same method as with libqt5-qtbase package: Qt itself already does runtime check whether subpixel rendering is available, but only when FT_CONFIG_OPTION_SUBPIXEL_RENDERING is defined. Thus it is enough to only remove that condition
• The -devel subpackage requires Mesa-devel, not only at build time
• Fixed compilation on SLE_11_SP3 by making it build against Mesa-devel on that system
• Replace patch l-qclipboard_fix_recursive.patch with qtcore-4.8.5-qeventdispatcher-recursive.patch. The later one seems to work better and really resolves the issue in LibreOffice
• Added kde4_qt_plugin_path.patch, so kde4 plugins are magically found/known outside kde4 enviroment/session
• added _constraints. building took up to 7GB of disk space on s390x, and more than 6GB on x86_64
• Add 3 patches for Qt bugs to make LibreOffice KDE4 file picker work properly again:
  • Add glib-honor-ExcludeSocketNotifiers-flag.diff (QTBUG-37380)
  • Add l-qclipboard_fix_recursive.patch (QTBUG-34614)
  • Add l-qclipboard_delay.patch (QTBUG-38585)

This security update fixes the following issues:

• Add libqt5-Fix-a-division-by-zero-processing-malformed-BMP.patch
  • QTBUG-44547, bsc#921999 (CVE-2015-0295)
• Add libqt5-Fixes-crash-in-bmp-and-ico-image-decoding.patch
  • bsc#927806 (CVE-2015-1858), bsc#927807 (CVE-2015-1859)
• Add libqt5-Fixes-crash-in-gif-image-decoder.patch
  • bsc#927808 (CVE-2015-1860)
• Add libqt5-fix-use-after-free-bug.patch from upstream
  • fixes the use-after-free bug in backingstore, boo#870151

Multiple buffer overflows in gui/image/qbmphandler.cpp in the QtBase module in Qt before 4.8.7 and 5.x before 5.4.2 allow remote attackers to cause a denial of service (segmentation fault and crash) and possibly execute arbitrary code via a crafted BMP image.

Wolfgang Schenk discovered that Qt incorrectly handled certain malformed GIF images. If a user or automated system were tricked into opening a specially crafted GIF image, a remote attacker could use this issue to cause Qt to crash, resulting in a denial of service. This issue only applied to Ubuntu 12.04 LTS and Ubuntu 14.04 LTS. (CVE-2014-0190)

Fabian Vogt discovered that Qt incorrectly handled certain malformed BMP images. If a user or automated system were tricked into opening a specially crafted BMP image, a remote attacker could use this issue to cause Qt to crash, resulting in a denial of service. (CVE-2015-0295)

Richard Moore and Fabian Vogt discovered that Qt incorrectly handled certain malformed BMP images. If a user or automated system were tricked into opening a specially crafted BMP image, a remote attacker could use this issue to cause Qt to crash, resulting in a denial of service, or possibly execute arbitrary code. (CVE-2015-1858)

Richard Moore and Fabian Vogt discovered that Qt incorrectly handled certain malformed ICO images. If a user or automated system were tricked into opening a specially crafted ICO image, a remote attacker could use this issue to cause Qt to crash, resulting in a denial of service, or possibly execute arbitrary code. (CVE-2015-1859)
