Security Bulletin: Vulnerabilities in Open Source OpenSSL affects the IBM FlashSystem models 840 and 900 (CVE-2015-1788, CVE-2015-1789, CVE-2015-1791, and CVE-2015-3216)

Summary

There are vulnerabilities in the Open Source OpenSSL version that is used by the IBM® FlashSystem™ 840 and IBM FlashSystem 900. An exploit of these vulnerabilities could result in a denial of service. One vulnerability can result in a race condition, the result of which is of unknown impact.

Vulnerability Details

CVEID: 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 Environmental Score*: Undefined
CVSS Vector: (AV:N/AC:L/Au:N/C:N/I:N/A:P)

CVEID: CVE-2015-1789 DESCRIPTION: OpenSSL is vulnerable to a denial of service, caused by an out-of-bounds read in X509_cmp_time. An attacker could exploit this vulnerability using a specially crafted certificate or CRL to trigger a segmentation fault.
CVSS Base Score: 5
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)

CVEID: 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.
