SynopsisThe remote Amazon Linux AMI host is missing a security update.
DescriptionA denial of service flaw was found in the way the File Information (fileinfo) extension handled indirect rules. A remote attacker could use this flaw to cause a PHP application using fileinfo to crash or consume an excessive amount of CPU.
The gdImageCrop function in ext/gd/gd.c in PHP 5.5.x before 5.5.9 does not check return values, which allows remote attackers to cause a denial of service (application crash) or possibly have unspecified other impact via invalid imagecrop arguments that lead to use of a NULL pointer as a return value, a different vulnerability than CVE-2013-7226 .
SolutionRun 'yum update php55' to update your system.
