*The CVSS Environment Score is customer environment specific and will ultimately impact the Overall CVSS Score. Customers can evaluate the impact of this vulnerability in their environments by accessing the links in the Reference section of this Security Bulletin.
According to the Forum of Incident Response and Security Teams (FIRST), the Common Vulnerability Scoring System (CVSS) is an “industry open standard designed to convey vulnerability severity and help to determine urgency and priority of response.” IBM PROVIDES THE CVSS SCORES ““AS IS”” WITHOUT WARRANTY OF ANY KIND, INCLUDING THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. CUSTOMERS ARE RESPONSIBLE FOR ASSESSING THE IMPACT OF ANY ACTUAL OR POTENTIAL SECURITY VULNERABILITY. In addition to other efforts to address potential vulnerabilities, IBM periodically updates the record of components contained in our product offerings. As part of that effort, if IBM identifies previously unidentified packages in a product/service inventory, we address relevant vulnerabilities regardless of CVE date. Inclusion of an older CVEID does not demonstrate that the referenced product has been used by IBM since that date, nor that IBM was aware of a vulnerability as of that date. We are making clients aware of relevant vulnerabilities as we become aware of them. “Affected Products and Versions” referenced in IBM Security Bulletins are intended to be only products and versions that are supported by IBM and have not passed their end-of-support or warranty date. Thus, failure to reference unsupported or extended-support products and versions in this Security Bulletin does not constitute a determination by IBM that they are unaffected by the vulnerability. Reference to one or more unsupported versions in this Security Bulletin shall not create an obligation for IBM to provide fixes for any unsupported or extended-support products or versions.
CVEID: CVE-2018-1301**
DESCRIPTION:** Apache HTTPD is vulnerable to a denial of service, caused by an out-of-bounds access error after a header size limit has been reached reading the HTTP header. By sending a specially crafted HTTP request, an attacker could exploit this vulnerability to cause the service to crash.
CVSS Base Score: 5.3
CVSS Temporal Score: See https://exchange.xforce.ibmcloud.com/vulnerabilities/140852 for the current score
CVSS Environmental Score*: Undefined
CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:L)
CVEID: CVE-2017-15715**
DESCRIPTION:** Apache HTTPD could allow a remote attacker to bypass security restrictions, caused by the < FilesMatch > expression matching ‘$’ to a newline character in a malicious filename instead of the end of the filename. By matching the trailing portion of the filename, an attacker could exploit to bypass security controls that use the < FilesMatch > directive.
CVSS Base Score: 3.7
CVSS Temporal Score: See https://exchange.xforce.ibmcloud.com/vulnerabilities/140857 for the current score

CVEID: CVE-2017-15710**
DESCRIPTION:** Apache HTTPD is vulnerable to a denial of service, caused by an out-of-bounds memory write error. By sending a specially crafted Accept-Language header value, an attacker could exploit this vulnerability to cause the service to crash.
