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 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/101674 for the current
score
CVSS Environmental Score*: Undefined
CVSS Vector: (AV:N/AC:L/Au:N/C:P/I:P/A:P)
CVEID: CVE-2015-0286
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 could allow a remote attacker to execute arbitrary code
on the system, 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 execute arbitrary code on the system.
CVSS Base Score: 7.5
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:P/I:P/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
