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.
CVSS Vector: (CVSS:3.0/AV:N/AC:H/PR:N/UI:N/S:U/C:N/I:L/A:N)

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 Vector: (CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:L)

CVEID:   CVE-2019-0211
DESCRIPTION:   Apache HTTP Server could allow a local authenticated attacker to gain elevated privileges on the system, caused by the execution of code in less-privileged child processes or threads from modules' scripts. By manipulating the scoreboard, an attacker could exploit this vulnerability to execute arbitrary code on the system with root privileges.
