Security Bulletin: Multiple vulnerabilities in OpenSSL affect IBM Security Network Protection

Summary

There are multiple vulnerabilities in OpenSSL that is used by IBM Security Network Protection. These vulnerabilities include CVE-2014-8176, CVE-2015-1789, CVE-2015-1790, CVE-2015-1791, CVE-2015-1792, CVE-2015-3216, and CVE-2015-1788.

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&gt; 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 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.

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.

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&gt; for the current score

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 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.
