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 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: 5.0

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 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: 5.0

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
