Security Bulletin
Summary
A fix is available for IBM SONAS, for the security vulnerabilities in Network Time Protocol (NTP) being used.
Vulnerability Details
Network Time Protocol (NTP) is used in IBM SONAS for synchronizing time.
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
CVSS Temporal Score: See http://xforce.iss.net/xforce/xfdb/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
CVSS Temporal Score: See http://xforce.iss.net/xforce/xfdb/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: 7.5
CVSS Temporal Score: See http://xforce.iss.net/xforce/xfdb/99578 for the current score
CVSS Environmental Score*: Undefined
CVSS Vector: (AV:N/AC:L/Au:N/C:P/I:P/A:P)
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
CVSS Temporal Score: See http://xforce.iss.net/xforce/xfdb/99579 for the current score
CVSS Environmental Score*: Undefined
CVSS Vector: (AV:N/AC:L/Au:N/C:N/I:N/A:P)
