PHP 5.6.x < 5.6.12 Multiple Vulnerabilities

Versions of PHP 5.6.x earlier than 5.6.12 are vulnerable to the following issues :

• A flaw exists in the file ‘gd.c’ due to the improper handling of images with large negative coordinates by the imagefilltoborder() function. An attacker can exploit this to cause a stack overflow, thus crashing an application using PHP.
• A flaw exists in the file ‘php_odbc.c’ when the odbc_fetch_array() function handles columns that are defined as NVARCHAR(MAX). An attacker can exploit this to crash an application using PHP.
