Security Bulletin: Multiple vulnerabilities in ntp affect IBM Flex System Manager (FSM) (CVE-2014-9293, CVE-2014-9294, CVE-2014-9297, CVE-2014-9298)

Vulnerability Details

Summary

There are multiple vulnerabilities in ntp that is used by IBM Flex System Manager.

Vulnerability Details:

CVE-ID: CVE-2014-9293

Description: Network Time Protocol (NTP) Project NTP daemon (ntpd) could provide weaker than expected security, caused by the improper generation of a key by the config_auth function when an auth key is not configured. A remote attacker could exploit this vulnerability using brute force techniques to guess the generated key.

CVSS Base Score: 5.00
CVSS Temporal Score: See http://exchange.xforce.ibmcloud.com/vulnerabilities/99576 for current score
CVSS Environmental Score*: Undefined
CVSS Vector: (AV:N/AC:L/Au:N/C:N/I:P/A:N)

CVE-ID: CVE-2014-9294

Description: Network Time Protocol (NTP) Project NTP daemon (ntpd) could provide weaker than expected security, caused by the use of a weak RNG seed by ntp-keygen.c. A remote attacker could exploit this vulnerability using brute force techniques to defeat cryptographic protection mechanisms.

CVSS Base Score: 5.00
CVSS Temporal Score: See http://exchange.xforce.ibmcloud.com/vulnerabilities/99577 for current score
CVSS Environmental Score*: Undefined
CVSS Vector: (AV:N/AC:L/Au:N/C:N/I:P/A:N)

CVE-ID: CVE-2014-9297

Description: Network Time Protocol (NTP) Project NTP daemon (ntpd) could allow a remote attacker to conduct spoofing attacks, caused by insufficient entropy in PRNG. An attacker could exploit this vulnerability to spoof the IPv6 address ::1 to bypass ACLs and launch further attacks on the system.

CVSS Base Score: 5.00
CVSS Temporal Score: See http://exchange.xforce.ibmcloud.com/vulnerabilities/100004 for current score

CVSS Vector: (AV:N/AC:L/Au:N/C:N/I:P/A:N)

CVE-ID: CVE-2014-9298

Description: Network Time Protocol (NTP) Project NTP daemon (ntpd) could allow a remote attacker to obtain sensitive information, caused by the improper validation of the length value in extension field pointers. An attacker could exploit this vulnerability to obtain sensitive information.

CVSS Base Score: 5.00
