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&gt; 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&gt; 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&gt; 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&gt; 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/91910&gt; for the current score
CVSS Environmental Score*: Undefined
