CVEID:

CVE-2016-0799

DESCRIPTION:

OpenSSL could allow a remote attacker to obtain sensitive information, caused
by a memory error in the BIO_*printf() functions. An attacker could exploit
this vulnerability using specially crafted data to trigger an out-of-bounds
read.

CVSS Base Score: 3.7

CVSS Temporal Score: See

https://exchange.xforce.ibmcloud.com/vulnerabilities/111143

CVEID:

CVE-2016-2105

DESCRIPTION:

OpenSSL is vulnerable to a heap-based buffer overflow, caused by improper
bounds checking by the EVP_EncodeUpdate() function. By sending an overly long
argument, a remote attacker could overflow a buffer and execute arbitrary
code on the system or cause the application to crash.

CVSS Base Score: 5.6

CVE-2016-2106

DESCRIPTION:

OpenSSL is vulnerable to a heap-based buffer overflow, caused by improper
bounds checking by the EVP_EncryptUpdate() function. By sending an overly
long argument, a remote attacker could overflow a buffer and execute
arbitrary code on the system or cause the application to crash.

CVSS Base Score: 5.6

CVSS Temporal Score: See

https://exchange.xforce.ibmcloud.com/vulnerabilities/112856

for the current score

CVSS Environmental Score*: Undefined

CVSS Vector: (CVSS:3.0/AV:N/AC:H/PR:N/UI:N/S:U/C:L/I:L/A:L)

CVEID:

CVE-2016-2107

DESCRIPTION:

OpenSSL could allow a remote attacker to obtain sensitive information, caused
by an error when the connection uses an AES CBC cipher and the server support
AES-NI. A remote user with the ability to conduct a man-in-the-middle attack
could exploit this vulnerability via the POODLE (Padding Oracle On Downgraded
Legacy Encryption) attack to decrypt traffic.

CVSS Base Score: 4.3

CVSS Temporal Score: See

https://exchange.xforce.ibmcloud.com/vulnerabilities/112854

CVSS Environmental Score*: Undefined

CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:N/UI:R/S:U/C:L/I:N/A:N)

CVEID:

CVE-2016-2108

DESCRIPTION:

OpenSSL could allow a remote attacker to execute arbitrary code on the
system, caused by a buffer underflow when deserializing untrusted ASN.1
structures. An attacker could exploit this vulnerability to corrupt memory
and trigger an out-of-bounds write and execute arbitrary code on the system.

CVE-2016-2109

DESCRIPTION:

OpenSSL is vulnerable to a denial of service, caused by a memory allocation
error. By reading specially crafted ASN.1 data from a BIO using functions
such as d2i_CMS_bio(), an attacker could exploit this vulnerability to
consume all available resources and exhaust memory.

CVEID:

CVE-2016-2842

DESCRIPTION:

OpenSSL is vulnerable to a denial of service, caused by the failure to verify
that a certain memory allocation succeeds by the doapr_outch function. A
remote attacker could exploit this vulnerability using a specially crafted
string to cause an out-of-bounds write or consume an overly large amount of
resources.

CVSS Base Score: 7.5

CVSS Temporal Score: See

https://exchange.xforce.ibmcloud.com/vulnerabilities/111304

attacker could exploit this vulnerability using unknown attack vectors to
execute arbitrary code on the vulnerable system or cause a denial of service.

CVSS Base Score: 8.8

CVSS Temporal Score: See

https://exchange.xforce.ibmcloud.com/vulnerabilities/111321

CVEID:

CVE-2016-1979

DESCRIPTION:

Mozilla Firefox could allow a remote attacker to execute arbitrary code on
the system, caused by a use-after-free when processing DER encoded keys in
the Network Security Services (NSS) libraries. By persuading a victim to
visit a specially-crafted Web site, a remote attacker could exploit this
vulnerability using unknown attack vectors to execute arbitrary code on the
vulnerable system or cause a denial of service.

CVSS Base Score: 8.8
