Synopsis
The version of PHP running on the remote web server is affected by multiple vulnerabilities.Description
According to its banner, the version of PHP running on the remote web server is 7.0.x prior to 7.0.19. It is, therefore, affected by the following vulnerabilities :- A memory allocation issue exists in the zend_string_extend() function in file Zend/zend_string.h when concatenating strings due to a failure to prevent changes to string objects that result in a negative length. An unauthenticated, remote attacker can exploit this to cause a denial of service condition or possibly other unspecified impact. (CVE-2017-8923)
- A memory allocation issue exists in the i_zval_ptr_dtor() function in Zend/zend_variables.h when allocating large amounts of memory. An unauthenticated, remote attacker can exploit this, via crafted operations on array data structures, to cause a denial of service condition. (CVE-2017-9119)
