Due to flaws in the embedded copy of libDCR, a fork of dcraw.c, in the embedded copy of CxImage, opening a specially crafted photo file could trigger a division by zero, an infinite loop, or a null pointer dereference, resulting in a denial of service (CVE-2013-1438).
This update fixes those flaws.
XBMC is also updated to a newer bugfix-only release, version 12.3. It contains fixes to various issues, including: - several PVR related bugs - memory leaks - audio channel mapping - possible crash on progress dialog and more.
Additionally, this update fixes a compatibility issue on Mageia 4 affecting AC-3 transcoding, which prevented, for example, multichannel playback of AAC 5.1 files over S/PDIF or stereo-only HDMI devices.
The PVR addons have also been updated.
