the applicable CVEs.

Vulnerability Details


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

CVSS Temporal Score: See

https://exchange.xforce.ibmcloud.com/vulnerabilities/112855

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-2016-2106

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-2016-2108

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 and later reserializes them. An attacker could exploit this
vulnerability to corrupt memory and trigger an out-of-bounds write and
execute arbitrary code on the system.

CVSS Base Score: 8.1

CVSS Temporal Score: See

https://exchange.xforce.ibmcloud.com/vulnerabilities/112853

for the current score

CVSS Environmental Score*: Undefined

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

CVEID:

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.

CVSS Base Score: 5.3

CVSS Temporal Score: See

https://exchange.xforce.ibmcloud.com/vulnerabilities/112857

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)
