SynopsisThe remote Amazon Linux AMI host is missing a security update.
DescriptionA vulnerability was found in gd. Integer underflow in a calculation in dynamicGetbuf() was incorrectly handled, leading in some circumstances to an out of bounds write through a very large argument to memcpy().
An attacker could create a crafted image that would lead to a crash or, potentially, code execution. (CVE-2016-8670)
Use-after-free vulnerability in the CURLFile implementation in ext/curl/curl_file.c in PHP before 5.6.27 allows remote attackers to cause a denial of service or possibly have unspecified other impact via crafted serialized data that is mishandled during __wakeup processing. (CVE-2016-9137)
Stack consumption vulnerability in the gdImageFillToBorder function in gd.c in the GD Graphics Library (aka libgd) before 2.2.2, as used in PHP before 5.6.28, allows remote attackers to cause a denial of service (segmentation violation) via a crafted imagefilltoborder call that triggers use of a negative color value. (CVE-2016-9933)
ext/wddx/wddx.c in PHP before 5.6.28 allows remote attackers to cause a denial of service (NULL pointer dereference) via crafted serialized data in a wddxPacket XML document, as demonstrated by a PDORow string.
The php_wddx_push_element function in ext/wddx/wddx.c in PHP before 5.6.29 allows remote attackers to cause a denial of service (out-of-bounds read and memory corruption) or possibly have unspecified other impact via an empty boolean element in a wddxPacket XML document. (CVE-2016-9935)
