Security Bulletin


Summary

Multiple vulnerabilities in NTP, Hivex, glibc, libuser, BIND, affect IBM SmartCloud Provisioning 2.1 for IBM Software Virtual Appliance (CVE-2014-9297, CVE-2014-9298, CVE-2014-9273, CVE-2013-7424, CVE-2015-3245, CVE-2015-3246, CVE-2015-5477).

Vulnerability Details

CVEID: 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
CVSS Temporal Score: See https://exchange.xforce.ibmcloud.com/vulnerabilities/100004 for the current score
CVSS Environmental Score*: Undefined
CVSS Vector: (AV:N/AC:L/Au:N/C:N/I:P/A:N)

CVEID: CVE-2014-9298
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
CVSS Temporal Score: See https://exchange.xforce.ibmcloud.com/vulnerabilities/100005 for the current score
CVSS Environmental Score*: Undefined
CVSS Vector: (AV:N/AC:L/Au:N/C:P/I:N/A:N)

CVEID: CVE-2014-9273
DESCRIPTION:
Hivex could allow a local attacker to bypass security restrictions, caused by the failure to properly handle small-sized hive files in lib/handle.c. An attacker could exploit this vulnerability to gain privileges and execute arbitrary code on the system.
CVSS Base Score: 4.4
CVSS Temporal Score: See
https://exchange.xforce.ibmcloud.com/vulnerabilities/99725 for the current score
CVSS Environmental Score*: Undefined
CVSS Vector: (AV:L/AC:M/Au:N/C:P/I:P/A:P)

CVEID: CVE-2013-7424
DESCRIPTION:
The GNU C Library (glibc) could allow a remote attacker to execute arbitrary code on the system, caused by an invalid free error in the getaddrinfo() function when used with the AI_IDN flag. An attacker able to make an application call this function could exploit this vulnerability to execute arbitrary code on the system.
CVSS Base Score: 5.1
CVSS Temporal Score: See https://exchange.xforce.ibmcloud.com/vulnerabilities/101073 for the current score
CVSS Environmental Score*: Undefined
CVSS Vector: (AV:N/AC:H/Au:N/C:P/I:P/A:P)

CVEID: CVE-2015-3245
DESCRIPTION:
libuser is vulnerable to a denial of service, caused by the failure to properly filter out newline characters by the chfn() function within the userhelper utility. A local authenticated attacker could exploit this vulnerability to inject newline characters into the /etc/passwd file and cause a denial of service.
CVSS Base Score: 4.7
CVSS Temporal Score: See https://exchange.xforce.ibmcloud.com/vulnerabilities/105022 for the current score
CVSS Environmental Score*: Undefined
CVSS Vector: (AV:L/AC:H/PR:L/UI:N/S:U/C:N/I:N/A:H)

CVEID: CVE-2015-3246
DESCRIPTION:
libuser could allow a local authenticated attacker to gain elevated privileges on the system, caused by the improper handling of the /etc/passwd file. An attacker could exploit this vulnerability to gain root privileges on the system.
CVSS Base Score: 7.8
CVSS Temporal Score: See https://exchange.xforce.ibmcloud.com/vulnerabilities/105023 for the current score
CVSS Environmental Score*: Undefined
CVSS Vector: (AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H)

CVEID: CVE-2015-5477
DESCRIPTION:
ISC BIND is vulnerable to a denial of service, caused by an error in the handling of TKEY queries. By sending specially-crafted packets, a remote attacker could exploit this vulnerability to cause a REQUIRE assertion failure.
CVSS Base Score: 7.5
CVSS Temporal Score: See https://exchange.xforce.ibmcloud.com/vulnerabilities/105120 for the current score
CVSS Environmental Score*: Undefined
