DESCRIPTION: Network Time Protocol (NTP) Project NTP daemon (ntpd) could allow
a remote attacker to bypass security restrictions, caused by the acceptance of
packets that do not contain a message authentication code (MAC) as valid
packets wen configured for symmetric key authentication. An attacker could
exploit this vulnerability using man-in-the-middle techniques to bypass the
authentication process.
CVSS Base Score: 5.4
CVSS Temporal Score: See
https://exchange.xforce.ibmcloud.com/#/vulnerabilities/102051 for the current
score
CVSS Environmental Score*: Undefined
CVSS Vector: (AV:A/AC:M/Au:N/C:P/I:P/A:P)
CVEID: CVE-2015-1799
DESCRIPTION: Network Time Protocol (NTP) Project NTP daemon (ntpd) is
vulnerable to a denial of service, caused by an error when using symmetric key
authentication. By sending specially-crafted packets to both peering hosts, an
attacker could exploit this vulnerability to prevent synchronization.
CVSS Base Score: 5.4
CVSS Temporal Score: See
https://exchange.xforce.ibmcloud.com/#/vulnerabilities/102052 for the current
score
CVSS Environmental Score*: Undefined
CVSS Vector: (AV:A/AC:M/Au:N/C:P/I:P/A:P)
CVEID: CVE-2015-1819
DESCRIPTION: Libxml is vulnerable to a denial of service, caused by an XML
External Entity Injection (XXE) error in the xmlreader when processing XML
data. A remote attacker could exploit this vulnerability to consume all
available memory resources.

CVEID: CVE-2015-2017
DESCRIPTION: The IBM WebSphere Portal is vulnerable to HTTP response splitting
attacks. A remote attacker could exploit this vulnerability using
specially-crafted URL to 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, cross-site scripting, and possibly obtain sensitive
infrmation.

DESCRIPTION: Mozilla Firefox could allow a remote attacker to bypass security
restrictions, caused by the failure to properly handle certain exceptional
cases by the Elliptical Curve Cryptography (ECC) multiplication for Elliptic
Curve Digital Signature Algorithm (ECDSA) signature validation in Network
Security Services (NSS). By persuading a victim to visit a specially-crafted
Web site, a remote attacker could exploit this vulnerability to forge
signatures.
