Summary
OpenSSL vulnerabilities were disclosed on March 19, 2015 by the OpenSSL
Project. OpenSSL is used by IBM Security Access Manager for Web. IBM Security
Access Manager for Web has addressed the applicable CVEs.
Vulnerability Details
CVEID: CVE-2015-0209
DESCRIPTION: OpenSSL could allow a remote attacker to execute arbitrary code
on the system, caused by a use-after-free error in the d2i_ECPrivateKey or
EVP_PKCS82PKEY function. An attacker could exploit this vulnerability using a
malformed Elliptic Curve (EC) private-key file to corrupt memory and execute
arbitrary code on the system and cause a denial of service.
CVSS Base Score: 6.8
CVSS Temporal Score: See
https://exchange.xforce.ibmcloud.com/#/vulnerabilities/101674 for the current
score
CVSS Environmental Score*: Undefined
CVSS Vector: (AV:N/AC:M/Au:N/C:P/I:P/A:P)
CVEID: CVE-2015-0286
DESCRIPTION: OpenSSL is vulnerable to a denial of service, caused by an error
in the ASN1_TYPE_cmp function when attempting to compare ASN.1 boolean types.
An attacker could exploit this vulnerability to crash any certificate
verification operation and cause a denial of service.
CVSS Base Score: 5
CVSS Temporal Score: See
https://exchange.xforce.ibmcloud.com/#/vulnerabilities/101666 for the current
score
CVSS Environmental Score*: Undefined
CVSS Vector: (AV:N/AC:L/Au:N/C:N/I:N/A:P)
CVEID: CVE-2015-0287
DESCRIPTION: OpenSSL is vulnerable to a denial of service, caused by an error
related to the reuse of a structure in ASN.1 parsing. An attacker could
exploit this vulnerability using an invalid write to corrupt memory and cause
a denial of service.
CVSS Base Score: 5
CVSS Temporal Score: See
https://exchange.xforce.ibmcloud.com/#/vulnerabilities/101668 for the current
score
CVSS Environmental Score*: Undefined
CVSS Vector: (AV:N/AC:L/Au:N/C:N/I:N/A:P)
CVEID: CVE-2015-0288
DESCRIPTION: OpenSSL is vulnerable to a denial of service, caused by an error
in the X509_to_X509_REQ function. An attacker could exploit this vulnerability
to trigger a NULL pointer dereference.
CVSS Base Score: 5
CVSS Temporal Score: See
https://exchange.xforce.ibmcloud.com/#/vulnerabilities/101675 for the current
score
CVSS Environmental Score*: Undefined
CVSS Vector: (AV:N/AC:L/Au:N/C:N/I:N/A:P)
CVEID: CVE-2015-0289
DESCRIPTION: OpenSSL is vulnerable to a denial of service, caused by the
failure to properly handle missing outer ContentInfo by the PKCS#7 parsing
code. An attacker could exploit this vulnerability using a malformed
ASN.1-encoded PKCS#7 blob to trigger a NULL pointer dereference.
CVSS Base Score: 5
CVSS Temporal Score: See
https://exchange.xforce.ibmcloud.com/#/vulnerabilities/101669 for the current
score
CVSS Environmental Score*: Undefined
CVSS Vector: (AV:N/AC:L/Au:N/C:N/I:N/A:P)
CVEID: CVE-2015-0292
DESCRIPTION: OpenSSL could allow a remote attacker to execute arbitrary code
on the system, caused by an error when processing base64 encoded data. An
attacker could exploit this vulnerability using specially-crafted base 64 data
to corrupt memory and execute arbitrary code on the system and cause a denial
of service.
CVSS Base Score: 7.5
CVSS Temporal Score: See
https://exchange.xforce.ibmcloud.com/#/vulnerabilities/101670 for the current
score
CVSS Environmental Score*: Undefined
CVSS Vector: (AV:N/AC:L/Au:N/C:P/I:P/A:P)
CVEID: CVE-2015-0293
DESCRIPTION: OpenSSL is vulnerable to a denial of service. By sending a
specially-crafted SSLv2 CLIENT-MASTER-KEY message, a remote attacker could
exploit this vulnerability to trigger an assertion.
CVSS Base Score: 5
CVSS Temporal Score: See
https://exchange.xforce.ibmcloud.com/#/vulnerabilities/101671 for the current
score
