Summary
OpenSSL vulnerabilities were disclosed by the OpenSSL Project and affect IBM
NetInsight. This includes the alternate chains certificate forgery
vulnerability (CVE-2015-1793). IBM NetInsight has addressed the applicable
CVEs.
Vulnerability Details
CVEID: CVE-2015-1793
DESCRIPTION: OpenSSL could allow a remote attacker to bypass security
restrictions, caused by an implementation error of the alternative certificate
chain logic. An attacker could exploit this vulnerability to bypass the CA
flag and other specific checks on untrusted certificates and issue an invalid
certificate.
CVSS Base Score: 7.5
CVSS Temporal Score: See
https://exchange.xforce.ibmcloud.com/vulnerabilities/104500 for the current
score
CVSS Environmental Score*: Undefined
CVSS Vector: (AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:H/A:N)
CVEID: CVE-2014-8176
DESCRIPTION: OpenSSL could allow a remote 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
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)
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 Base Score: 5
CVSS Temporal Score: See
https://exchange.xforce.ibmcloud.com/vulnerabilities/103778 for the current
score
CVSS Environmental Score*: Undefined
CVSS Vector: (AV:N/AC:L/Au:N/C:N/I:N/A:P)
CVEID: CVE-2015-1789
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-2015-1790
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

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.
CVSS Base Score: 5

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)
CVEID: 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
