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-2016-2182
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-2016-6302
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-2016-6306
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-2016-7052
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)
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-2016-2181
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-2016-2177
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 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-2016-6303
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-2016-8610
DESCRIPTION: SSL/TLS protocol is vulnerable to a denial of service, caused
by an error when processing ALERT packets during a SSL handshake. By
sending specially-crafted packets, a remote attacker could exploit this
vulnerability to cause the application to stop responding.
CVSS Base Score: 7.5
CVSS Temporal Score: See
https://exchange.xforce.ibmcloud.com/vulnerabilities/118296 for the
