Vulnerability Details
CVE ID: CVE-2014-8176
DESCRIPTION: OpenSSL could allow a remote authenticated attacker to execute arbitrary code on the system, caused by an invalid free error when application data between the ChangeCipherSpec and Finished messages is received by the DTLS peer. An attacker could exploit this vulnerability to trigger a segmentation fault or possibly corrupt memory and execute arbitrary code on the system.
CVSS Base Score: 6.5
CVSS Temporal Score: See https://exchange.xforce.ibmcloud.com/#/vulnerabilities/103782 for the current score
CVSS Environmental Score*: Undefined
CVSS Vector: (AV:N/AC:L/Au:S/C:P/I:P/A:P)
CVE ID: CVE-2015-1789
DESCRIPTION: OpenSSL could allow a remote authenticated attacker to execute arbitrary code on the system, caused by an invalid free error when application data between the ChangeCipherSpec and Finished messages is received by the DTLS peer. An attacker could exploit this vulnerability to trigger a segmentation fault or possibly corrupt memory and execute arbitrary code on the system.
CVSS Base Score: 5.0
CVSS Temporal Score: See https://exchange.xforce.ibmcloud.com/#/vulnerabilities/103779 for the current score
CVSS Environmental Score*: Undefined
CVSS Vector: (AV:N/AC:L/Au:N/C:N/I:N/A:P)
CVE ID: CVE-2015-1790
DESCRIPTION: OpenSSL is vulnerable to a denial of service, caused by the improper handling of missing inner EncryptedContent by the PKCS#7 parsing code. An attacker could exploit this vulnerability using specially crafted ASN.1-encoded PKCS#7 blobs with missing content to trigger a NULL pointer dereference.
CVSS Base Score: 5.0
CVSS Temporal Score: See https://exchange.xforce.ibmcloud.com/#/vulnerabilities/103780 for the current score
CVSS Environmental Score*: Undefined
CVSS Vector: (AV:N/AC:L/Au:N/C:N/I:N/A:P)
CVE ID: CVE-2015-1791
DESCRIPTION: A double-free memory error in OpenSSL in the ssl3_get_new_session_ticket() function has an unknown impact. By returning a specially crafted NewSessionTicket message, an attacker could cause the client to reuse a previous ticket resulting in a race condition.
CVSS Base Score: 5.0
CVSS Temporal Score: See https://exchange.xforce.ibmcloud.com/#/vulnerabilities/103609 for the current score
CVSS Environmental Score*: Undefined
CVSS Vector: (AV:N/AC:L/Au:N/C:N/I:P/A:N)
CVE ID: CVE-2015-1792
DESCRIPTION: OpenSSL is vulnerable to a denial of service, caused by an error when verifying a signedData message. An attacker could exploit this vulnerability using an unknown hash function OID to cause the application to enter into an infinite loop.
CVSS Base Score: 5.0
CVSS Temporal Score: See https://exchange.xforce.ibmcloud.com/#/vulnerabilities/103781 for the current score
CVSS Environmental Score*: Undefined
CVSS Vector: (AV:N/AC:L/Au:N/C:N/I:N/A:P)
CVE ID: CVE-2015-3216
DESCRIPTION: OpenSSL shipped with Red Hat Enterprise Linux is vulnerable to a denial of service, caused by an out-of-bounds memory read error in ssleay_rand_bytes() function. By sending specially crafted data, a remote attacker could exploit this vulnerability to cause the application to crash.
CVSS Base Score: 5.0
CVSS Temporal Score: See https://exchange.xforce.ibmcloud.com/#/vulnerabilities/103915 for the current score
CVSS Environmental Score*: Undefined
CVSS Vector: (AV:N/AC:L/Au:N/C:N/I:N/A:P)
CVE ID: CVE-2015-1788
DESCRIPTION: OpenSSL is vulnerable to a denial of service, caused by an error when processing an ECParameters structure over a specially crafted binary polynomial field. A remote attacker could exploit this vulnerability to cause the application to enter into an infinite loop.
CVSS Base Score: 5.0
CVSS Temporal Score: See https://exchange.xforce.ibmcloud.com/#/vulnerabilities/103778 for the current score
