Security Bulletin
Summary
IBM Flex System Chassis Management Module (CMM) has addressed the following vulnerabilities in PHP.
Vulnerability Details
DESCRIPTION: PHP is vulnerable to cross-site scripting, caused by improper validation of user-supplied input by the Apache2 component. A remote attacker could exploit this vulnerability using the body of a "Transfer-Encoding: chunked" request to execute script in a victim's Web browser within the security context of the hosting Web site, once the URL is clicked. An attacker could use this vulnerability to steal the victim's cookie-based authentication credentials.
CVSS Base Score: 6.1
CVSS Temporal Score: See https://exchange.xforce.ibmcloud.com/vulnerabilities/149966
CVSS Environmental Score*: Undefined
CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:N/UI:R/S:C/C:L/I:L/A:N)
CVEID: CVE-2018-14883
DESCRIPTION: PHP is vulnerable to a heap-based buffer overflow, caused by improper bounds checking by the exif_thumbnail_extract function in exif.c. By sending a specially-crafted request, a remote attacker could overflow a buffer and execute arbitrary code on the system.
CVSS Base Score: 9.8
CVSS Temporal Score: See https://exchange.xforce.ibmcloud.com/vulnerabilities/147895 for the current score
CVSS Environmental Score*: Undefined
