Vulnerability Details

CVEID:CVE-2015-0208
DESCRIPTION:OpenSSL is vulnerable to a denial of service caused by an error in the signature verification routines. By sending an ASN.1 signature using the RSA PSS algorithm and invalid parameters 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: Seehttps://exchange.xforce.ibmcloud.com/#/vulnerabilities/101667for the current score
CVSS Environmental Score*: Undefined
CVSS Vector: (AV:N/AC:L/Au:N/C:N/I:N/A:P)

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: Seehttps://exchange.xforce.ibmcloud.com/#/vulnerabilities/101674for 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: Seehttps://exchange.xforce.ibmcloud.com/#/vulnerabilities/101666for 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: Seehttps://exchange.xforce.ibmcloud.com/#/vulnerabilities/101668for the current score
CVSS Environmental Score*: Undefined
CVSS Vector: (AV:N/AC:L/Au:N/C:P/I:P/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: Seehttps://exchange.xforce.ibmcloud.com/#/vulnerabilities/101669for 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: Seehttps://exchange.xforce.ibmcloud.com/#/vulnerabilities/101670for 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: Seehttps://exchange.xforce.ibmcloud.com/#/vulnerabilities/101671for the current score
CVSS Environmental Score*: Undefined
CVSS Vector: (AV:N/AC:L/Au:N/C:N/I:N/A:P)
