Integer overflow in the cdf_read_property_info function in cdf.c in file through 5.19, as used in the Fileinfo component in PHP before 5.4.32 and 5.5.x before 5.5.16, allows remote attackers to cause a denial of service (application crash) via a crafted CDF file. NOTE: this vulnerability exists because of an incomplete fix for CVE-2012-1571. http://web.nvd.nist.gov/view/vuln/detail?vulnId=CVE-2014-3587 Signed-off-by: Yue Tao <Yue.Tao@windriver.com> Signed-off-by: Martin Jansa <Martin.Jansa@gmail.com>
