OpenSSL is used by IBM Image Construction and Composition Tool. IBM Image
Construction and Composition Tool has addressed 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
