Security Bulletin
Summary
OpenSSL vulnerabilities were disclosed on September 22 and 26, 2016 by the
OpenSSL Project. OpenSSL is used by IBM Security Network Controller. IBM
Security Network Controller has addressed the applicable CVEs.
Vulnerability Details
CVEID: CVE-2016-6304
DESCRIPTION: OpenSSL is vulnerable to a denial of service, caused by multiple
memory leaks in t1_lib.c during session renegotiation. By sending an overly
large OCSP Status Request extension, a remote attacker could exploit this
vulnerability to consume all available memory resources.
CVSS Base Score: 7.5
CVSS Temporal Score: See
https://exchange.xforce.ibmcloud.com/vulnerabilities/117110 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:H)
CVEID: CVE-2016-6303
DESCRIPTION: OpenSSL is vulnerable to a denial of service, caused by an
integer overflow in the MDC2_Update function. By using unknown attack
vectors, a remote attacker could exploit this vulnerability to trigger an
out-of-bounds write and cause the application to crash.
CVSS Base Score: 5.3
CVSS Temporal Score: See
https://exchange.xforce.ibmcloud.com/vulnerabilities/117023 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-2016-6308
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-2016-2181
DESCRIPTION: OpenSSL is vulnerable to a denial of service, caused by an
error in the DTLS replay protection implementation. By sending a specially
crafted sequence number, a remote attacker could exploit this vulnerability
to cause valid packets to be dropped.
CVSS Base Score: 5.3
CVSS Temporal Score: See
https://exchange.xforce.ibmcloud.com/vulnerabilities/116344 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-2016-6309
DESCRIPTION: OpenSSL is vulnerable to a denial of service, caused by a
use-after-free when handling message sizes. By sending an overly large
message, a remote attacker could exploit this vulnerability to possibly
execute arbitrary code on the system or cause the application to crash.
CVSS Base Score: 5.3
CVSS Temporal Score: See
https://exchange.xforce.ibmcloud.com/vulnerabilities/117148 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-2016-7052
DESCRIPTION: OpenSSL is vulnerable to a denial of service, caused by a
missing CRL sanity check. By attempting to use CRLs, a remote attacker
could exploit this vulnerability to cause the application to crash.
CVSS Base Score: 5.3
CVSS Temporal Score: See
https://exchange.xforce.ibmcloud.com/vulnerabilities/117149 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)

Security Bulletin
Summary
Glibc vulnerabilities were found in IBM Security Network Controller. IBM
Security Network Controller has addressed the applicable CVEs.
Vulnerability Details
CVEID: CVE-2016-3706
DESCRIPTION: GNU C Library (glibc or libc6) is vulnerable to a denial
of service, caused by a stack-based buffer overflow by the getaddrinfo
function within sysdeps/posix/getaddrinfo.c. A remote attacker could
exploit this vulnerability to cause the application to crash.
CVSS Base Score: 5.3
CVSS Temporal Score: See
https://exchange.xforce.ibmcloud.com/vulnerabilities/114123 for the

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-2016-4429
DESCRIPTION: GNU C Library (glibc or libc6) is vulnerable to a stack-based
buffer overflow, caused by improper bounds checking by the clntudp_call
function within sunrpc/clnt_udp.c. By sending specially-crafted ICMP
and UDP packets, a remote attacker could overflow a buffer and execute
arbitrary code on the system or cause the application to crash.
CVSS Base Score: 7.3
