A 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. 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. Stack consumption vulnerability in the gdImageFillToBorder function in gd.c in the GD Graphics Library before 2.2.2, as used in PHP before 5.6.28, allows remote attackers to cause a denial of service via a crafted imagefilltoborder call that triggers use of a negative color value. ext/wddx/wddx.c in PHP before 5.6.28 allows remote attackers to cause a denial of service 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 or possibly have unspecified other impact via an empty boolean element in a wddxPacket XML document
