Summary
A vulnerability in Open Source Apache HTTP Server affects the PureSystems
Managers used by IBM PureApplication System.
Vulnerability Details
CVEID: CVE-2016-0736
DESCRIPTION:
Apache HTTPD could allow a remote attacker to obtain sensitive information,
caused by an error in mod_session_crypto. By sending specially crafted data,
a remote attacker could exploit this vulnerability via the POODLE (Padding
Oracle On Downgraded Legacy Encryption) attack to gain access and modify
session data.

CVEID: CVE-2016-2161
DESCRIPTION:
Apache HTTPD is vulnerable to a denial of service, caused by an error in
mod_auth_digest. By sending specially crafted data, a remote attacker could
exploit this vulnerability to cause the server to crash.

CVEID: CVE-2016-8743
DESCRIPTION:
Apache HTTPD is vulnerable to HTTP response splitting attacks, caused by
improper validation of user-supplied input. A remote attacker could exploit
this vulnerability to inject arbitrary HTTP headers and cause the server to
return a split response, once the URL is clicked. This would allow the
attacker to perform further attacks, such as Web cache poisoning or cross-
site scripting, and possibly obtain sensitive information.
