Vulnerability Details
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 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-2016-5195
DESCRIPTION: Linux Kernel could allow a local attacker to gain elevated
privileges on the system, caused by a race condition when handling the
copy-on-write (COW) breakage of private read-only memory mappings by the
memory subsystem. An attacker could exploit this vulnerability to gain write
access to read-only memory mappings and elevated privileges on the system.
Note: This vulnerability is known as the Dirty COW bug.
CVSS Base Score: 8.4
CVSS Temporal Score: See
https://exchange.xforce.ibmcloud.com/vulnerabilities/118170 for the current
score
CVSS Environmental Score*: Undefined
CVSS Vector: (CVSS:3.0/AV:L/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H)
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, 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-2016-6306
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-2016-2182
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 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-2016-2181
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
