Libquicktime:allocation failed in quicktime_read_info

Description

Libquicktime is a library for reading and writing quicktime/avi/mp4 files. It provides convenient access to quicktime files with a variety of supported codecs.

An allocation failed was found in function quicktime_read_info in lqt_quicktime.c, which allows attackers to cause a denial of service via a crafted file.
