Security Bulletin: IBM Netezza Host Management NTP vulnerabilities (CVE-2014-9293, CVE-2014-9294, CVE-2014-9295, CVE-2014-9296)

Summary

Multiple vulnerabilities were found in the Linux NTP component. RedHat released a patch to address these vulnerabilities.

Vulnerability Details

CVEID:_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 https://exchange.xforce.ibmcloud.com/vulnerabilities/99576 for the current score
CVSS Environmental Score*: Undefined
CVSS Vector: (AV:N/AC:L/Au:N/C:N/I:P/A:N)

CVEID:_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 https://exchange.xforce.ibmcloud.com/vulnerabilities/99577 for the current score
CVSS Environmental Score*: Undefined
CVSS Vector: (AV:N/AC:L/Au:N/C:N/I:P/A:N)

CVEID:_CVE-2014-9295 _

DESCRIPTION:

Network Time Protocol (NTP) Project NTP daemon (ntpd) is vulnerable to multiple stack-based buffer overflows, caused by improper bounds checking by ntpd. By sending specially-crafted packets, a remote attacker could overflow a buffer and execute arbitrary code on the system or cause the application to crash.

CVSS Base Score: 7.50
CVSS Temporal Score: See https://exchange.xforce.ibmcloud.com/vulnerabilities/99578 for the current score

CVEID:_CVE-2014-9296 _

DESCRIPTION:

Network Time Protocol (NTP) Project NTP daemon (ntpd) is vulnerable to a denial of service, caused by the continual execution of the receive function after detecting an error. By sending specially-crafted packets, a remote attacker could exploit this vulnerability to cause a denial of service.

CVSS Base Score: 5.00
