Summary

Open SSL is used by Power Hardware Management Console (HMC). HMC has addressed the applicable CVEs

Vulnerability Details

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&gt; 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-2016-2107**
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&gt; for the current score
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-2016-2105**
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&gt; 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&gt; 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-2016-2109**
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&gt; for the current score
CVSS Environmental Score*: Undefined
