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
