Summary
The MD5 "Sloth" vulnerability on TLS 1.2, glibc and OpenSSL are used by IBM
Netezza Firmware Diagnostics Tools. IBM Netezza Firmware Diagnostics Tools
has addressed the applicable CVEs.
Vulnerability Details
CVEID:
CVE-2015-7575
DESCRIPTION:
The TLS protocol could allow weaker than expected security caused by a
collision attack when using the MD5 hash function for signing a
ServerKeyExchange message during a TLS handshake. An attacker could exploit
this vulnerability using man-in-the-middle techniques to impersonate a TLS
server and obtain credentials.
CVSS Base Score: 7.1
CVSS Temporal Score: See
https://exchange.xforce.ibmcloud.com/vulnerabilities/109415
for the current score
CVSS Environmental Score*: Undefined
CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:L/A:N)
CVEID:
CVE-2015-7547
DESCRIPTION:
GNU C Library (glibc) is vulnerable to a stack-based buffer overflow, caused
by improper bounds checking by the nss_dns backend for the getaddrinfo()
function when performing dual A/AAAA DNS queries. By sending a specially
crafted DNS response, a remote attacker could overflow a buffer and execute
arbitrary code on the system or cause the application to crash.
CVSS Base Score: 8.1

CVEID:
CVE-2016-0705
DESCRIPTION:
OpenSSL is vulnerable to a denial of service, caused by a double-free error
when parsing DSA private keys. An attacker could exploit this vulnerability
to corrupt memory and cause a denial of service.
CVSS Base Score: 3.7

CVEID:
CVE-2016-0798
DESCRIPTION:
OpenSSL is vulnerable to a denial of service, caused by a memory leak in SRP
servers. An attacker could exploit this vulnerability using a specially
crafted username value to cause a denial of service.
CVSS Base Score: 3.7
CVSS Temporal Score: See
https://exchange.xforce.ibmcloud.com/vulnerabilities/111141

CVSS Vector: (CVSS:3.0/AV:N/AC:H/PR:N/UI:N/S:U/C:N/I:N/A:L)
CVEID:
CVE-2016-0797
DESCRIPTION:
OpenSSL is vulnerable to a denial of service, caused by a NULL pointer
dereference in the BN_hex2bn/BN_dec2bn() function. An attacker could exploit
this vulnerability using specially crafted data to cause a denial of service.
CVSS Base Score: 3.7

CVEID:
CVE-2016-0799
DESCRIPTION:
OpenSSL could allow a remote attacker to obtain sensitive information, caused
by a memory error in the BIO_*printf() functions. An attacker could exploit
this vulnerability using specially crafted data to trigger an out-of-bounds
read.
CVSS Base Score: 3.7
CVSS Temporal Score: See

CVEID:
CVE-2016-0702
DESCRIPTION:
OpenSSL could allow a local attacker to obtain sensitive information, caused
by a side-channel attack against a system based on the Intel Sandy-Bridge
microarchitecture. An attacker could exploit this vulnerability to recover
RSA keys.
CVSS Base Score: 2.9
CVSS Temporal Score: See

CVEID:
CVE-2016-2842
DESCRIPTION:
OpenSSL is vulnerable to a denial of service, caused by the failure to verify
that a certain memory allocation succeeds by the doapr_outch function. A
remote attacker could exploit this vulnerability using a specially crafted
string to cause an out-of-bounds write or consume an overly large amount of
resources.
CVSS Base Score: 7.5
CVSS Temporal Score: See

DESCRIPTION:
OpenSSL could allow a remote attacker to conduct man-in-the-middle attacks,
caused by an error related to the negotiation of disabled SSLv2 ciphers by
malicious SSL/TLS clients. An attacker could exploit this vulnerability to
conduct man-in-the-middle attacks.

Affected Products and Versions
IBM Netezza Firmware Diagnostics Tools 4.3.1.1 (and prior releases).
Remediation/Fixes
Upgrade the IBM Netezza Firmware Diagnostics Tools to 4.3.1.2
< Link to Fix Central >
Once updates have been applied, any process using glibc will need to be
restarted. Given that nearly all system processes use glibc, rebooting both
hosts after upgrading is suggested.
