Description

This security bulletin contains information about 2 vulnerabilities.


1) Code Injection (CVE-ID: CVE-2015-8835)

CWE-ID: CWE-94 - Improper Control of Generation of Code ('Code Injection')

CVSSv4: CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:U/U:Green


The vulnerability allows a remote attacker to execute arbitrary code on the target system.

The vulnerability exists due to improper input validation in make_http_soap_request() function within the "ext/soap/php_http.c" PHP SOAP extension when retrieving keys. A remote attacker can pass specially crafted serialized data that represent a numerically indexed _cookies array, related to the SoapClient::__call method in ext/soap/soap.c and execute arbitrary code on the target system.

Successful exploitation of this vulnerability may result in complete compromise of vulnerable system


2) Input validation error (CVE-ID: CVE-2015-8873)

CWE-ID: CWE-20 - Improper input validation

CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N/E:U/U:Green


The vulnerability allows a remote non-authenticated attacker to perform a denial of service (DoS) attack.

Stack consumption vulnerability in Zend/zend_exceptions.c in PHP before 5.4.44, 5.5.x before 5.5.28, and 5.6.x before 5.6.12 allows remote attackers to cause a denial of service (segmentation fault) via recursive method calls.
