Vulnerability Details

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
https://exchange.xforce.ibmcloud.com/vulnerabilities/117024
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-2016-6304
DESCRIPTION:
OpenSSL is vulnerable to a denial of service. By repeatedly requesting
renegotiation, a remote authenticated attacker could send an overly large
OCSP Status Request extension to consume all available memory resources.
CVSS Base Score: 6.5
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:L/UI:N/S:U/C:N/I:N/A:H)

CVEID: CVE-2016-2182
DESCRIPTION:
OpenSSL is vulnerable to a denial of service, caused by an out-of-bounds
write in the TS_OBJ_print_bio function in crypto/bn/bn_print.c. A remote
attacker could exploit this vulnerability using a specially crafted value to
cause the application to crash.
CVSS Base Score: 4.3
CVSS Temporal Score: See
https://exchange.xforce.ibmcloud.com/vulnerabilities/116342
for the current score
CVSS Environmental Score*: Undefined
CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:N/UI:R/S:U/C:N/I:N/A:L)

CVEID: CVE-2016-2180
DESCRIPTION:
OpenSSL is vulnerable to a denial of service, caused by an out-of-bounds read
in the TS_OBJ_print_bio function. A remote attacker could exploit this
vulnerability using a specially crafted time-stamp file to cause the
application to crash.
CVSS Base Score: 7.5
CVSS Temporal Score: See
https://exchange.xforce.ibmcloud.com/vulnerabilities/115829
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-2016-2177
DESCRIPTION:
OpenSSL is vulnerable to a denial of service, caused by the incorrect use of
pointer arithmetic for heap-buffer boundary checks. By leveraging unexpected
malloc behavior, a remote attacker could exploit this vulnerability to
trigger an integer overflow and cause the application to crash.
CVSS Base Score: 5.9
CVSS Temporal Score: See
https://exchange.xforce.ibmcloud.com/vulnerabilities/113890
for the current score
CVSS Environmental Score*: Undefined
CVSS Vector: (CVSS:3.0/AV:N/AC:H/PR:N/UI:N/S:U/C:N/I:N/A:H)

CVEID: CVE-2016-2178
DESCRIPTION:
OpenSSL could allow a remote attacker to obtain sensitive information, caused
by an error in the DSA implementation that allows the following of a non-
constant time codepath for certain operations. An attacker could exploit this
vulnerability using a cache-timing attack to recover the private DSA key.
CVSS Base Score: 5.3
CVSS Temporal Score: See
https://exchange.xforce.ibmcloud.com/vulnerabilities/113889
for the current score
CVSS Environmental Score*: Undefined
CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:N/A:N)

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

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

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-2016-2183
DESCRIPTION:
OpenSSL could allow a remote attacker to obtain sensitive information, caused
by an error in the in the Triple-DES on 64-bit block cipher, used as a part
of the SSL/TLS protocol. By capturing large amounts of encrypted traffic
between the SSL/TLS server and the client, a remote attacker able to conduct
a man-in-the-middle attack could exploit this vulnerability to recover the
plaintext data and obtain sensitive information. This vulnerability is known
as the SWEET32 Birthday attack.
CVSS Base Score: 3.7
CVSS Temporal Score: See
