A vulnerability in Open Source Apache HTTP Server affects the PureSystems
Managers used by IBM PureApplication System.

Vulnerability Details

CVEID: CVE-2017-7679
DESCRIPTION:
Apache HTTPD could allow a remote attacker to obtain sensitive information,
caused by a buffer overread in mod_mime. By sending a specially crafted
Content-Type response header, a remote attacker could exploit this
vulnerability to read one byte past the end of a buffer.
CVSS Base Score: 5.3
CVSS Temporal Score: See
https://exchange.xforce.ibmcloud.com/vulnerabilities/127420
for the current score
CVSS Environmental Score*: Undefined
CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:N/A:N)

CVEID: CVE-2017-3169
DESCRIPTION:
Apache HTTPD is vulnerable to a denial of service, caused by a NULL pointer
dereference in mod_ssl. By sending a specially crafted HTTP request to an
HTTPS port, a remote attacker could exploit this vulnerability to cause a
denial of service.
CVSS Base Score: 5.3
CVSS Temporal Score: See
https://exchange.xforce.ibmcloud.com/vulnerabilities/127417
