Security Bulletin
Summary
Glibc, GNU C and OpenSSL are used by IBM Netezza Firmware Diagnostics. IBM
Netezza Firmware Diagnostics Support Tools has addressed the applicable CVEs.
Vulnerability Details
CVEID: CVE-2016-1234
DESCRIPTION: glibc is vulnerable to a denial of service, caused
by a stack-based buffer overflow within the glob implementation when
GLOB_ALTDIRFUNC is used. A remote attacker could exploit this vulnerability
using an overly long name to overflow a buffer and cause the application
to crash.
CVSS Base Score: 5.3
CVSS Temporal Score: See
https://exchange.xforce.ibmcloud.com/vulnerabilities/111311 for the
current score
CVSS Environmental Score*: Undefined
CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:L)
CVEID: CVE-2016-2179
DESCRIPTION: OpenSSL is vulnerable to a denial of service. By sending
specially crafted DTLS record fragments to fill up buffer queues, a
remote attacker could exploit this vulnerability to open a large number
of simultaneous connections and consume all available memory resources.
CVSS Base Score: 5.3
CVSS Temporal Score: See
https://exchange.xforce.ibmcloud.com/vulnerabilities/116343 for the
current score
CVSS Environmental Score*: Undefined
CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:L)
CVEID: CVE-2016-6306
DESCRIPTION: OpenSSL is vulnerable to a denial of service, caused by missing
message length checks when parsing certificates. A remote authenticated
attacker could exploit this vulnerability to trigger an out-of-bounds read
and cause a denial of service.
CVSS Base Score: 4.3
CVSS Temporal Score: See
https://exchange.xforce.ibmcloud.com/vulnerabilities/117112 for the
current score
CVSS Environmental Score*: Undefined
CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:L)
CVEID: CVE-2016-6307
DESCRIPTION: OpenSSL is vulnerable to a denial of service, caused by a memory
allocation error in the logic prior to the excessive message length check. By
initiating multiple connection attempts, a remote authenticated attacker
could send an overly large message to exhaust all available memory resources.
CVSS Base Score: 4.3
CVSS Temporal Score: See
https://exchange.xforce.ibmcloud.com/vulnerabilities/117113 for the
current score
CVSS Environmental Score*: Undefined
CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:L)
CVEID: CVE-2016-6308
DESCRIPTION: OpenSSL is vulnerable to a denial of service, caused by
a memory allocation error in dtls1_preprocess_fragment() prior to the
excessive message length check. By initiating multiple connection attempts,
a remote authenticated attacker could send an overly large DTLS message
to exhaust all available memory resources.
CVSS Base Score: 4.3
CVSS Temporal Score: See
https://exchange.xforce.ibmcloud.com/vulnerabilities/117114 for the
current score
CVSS Environmental Score*: Undefined
CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:L)
CVEID: CVE-2016-6302
DESCRIPTION: OpenSSL is vulnerable to a denial of service, caused by the
failure to consider the HMAC size during validation of the ticket length
by the tls_decrypt_ticket function A remote attacker could exploit this
vulnerability using a ticket that is too short to cause a denial of service.
CVSS Base Score: 5.3
CVSS Temporal Score: See
