Security Bulletin
Summary
Vulnerablilities in the OpenSSL package affect IBM Security Proventia
Network Enterprise Scanner.
Vulnerability Details
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 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)
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
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)
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
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)
CVEID: 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)
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
