Summary
IBM Security Identity Manager Virtual Appliance (ISIM VA) has addressed the
following vulnerabilities due to buffer overflow, remote arbitrary code
execution, and denial of service.
Vulnerability Details
CVEID: CVE-2017-6464
DESCRIPTION: NTP is vulnerable to a denial of service. A remote authenticated
attacker could exploit this vulnerability using a malformed mode configuration
directive to cause the application to crash.
CVSS Base Score: 4.2
CVSS Temporal Score: See https://exchange.xforce.ibmcloud.com/vulnerabilities/
123610 for the current score
CVSS Environmental Score*: Undefined
CVSS Vector: (CVSS:3.0/AV:N/AC:H/PR:H/UI:R/S:U/C:N/I:N/A:H)
CVEID: CVE-2017-6463
DESCRIPTION: NTP is vulnerable to a denial of service. By sending an invalid
setting, a remote authenticated attacker could exploit this vulnerability
using the :config directive to cause the daemon to crash.
CVSS Base Score: 4.2
CVSS Temporal Score: See https://exchange.xforce.ibmcloud.com/vulnerabilities/
123612 for the current score
CVSS Environmental Score*: Undefined
CVSS Vector: (CVSS:3.0/AV:N/AC:H/PR:H/UI:R/S:U/C:N/I:N/A:H)
CVEID: CVE-2017-6462
DESCRIPTION: NTP is vulnerable to a denial of service, caused by a buffer
overflow in the legacy Datum Programmable Time Server refclock driver. By
sending specially crafted packets, a local authenticated attacker could
exploit this vulnerability to overflow a buffer and cause a denial of service.
CVSS Base Score: 1.6
CVSS Temporal Score: See https://exchange.xforce.ibmcloud.com/vulnerabilities/
123611 for the current score
CVSS Environmental Score*: Undefined
CVSS Vector: (CVSS:3.0/AV:P/AC:H/PR:H/UI:R/S:U/C:N/I:N/A:L)
CVEID: CVE-2015-3331
DESCRIPTION: Linux Kernel, built with the Intel AES-NI instructions for AES
algorithm support (CONFIG_CRYPTO_AES_NI_INTEL), is vulnerable to a buffer
overflow, caused by improper bounds checking by the RFC4106 GCM mode
decryption functionality. By sending fragmented packets using the Intel AES-NI
instruction, a remote attacker could overflow a buffer and execute arbitrary
code on the system with elevated privileges.
CVSS Base Score: 9.3
CVSS Temporal Score: See https://exchange.xforce.ibmcloud.com/vulnerabilities/
103483 for the current score
CVSS Environmental Score*: Undefined
CVSS Vector: (AV:N/AC:M/Au:N/C:C/I:C/A:C)
CVEID: CVE-2014-2523
DESCRIPTION: Linux Kernel could allow a remote attacker to execute arbitrary
code on the system, caused by an error in the /netfilter/
nf_conntrack_proto_dccp.c file. By sending a specially-crafted DCCP packet, an
attacker could exploit this vulnerability to corrupt kernel stack memory and
execute arbitrary code on the system with kernel privileges.
CVSS Base Score: 10
CVSS Temporal Score: See https://exchange.xforce.ibmcloud.com/vulnerabilities/
