Vulnerability Details

CVEID:

CVE-2015-3193

DESCRIPTION:

OpenSSL could allow a remote attacker to obtain sensitive information, caused
by an error in the x86_64 Montgomery squaring procedure. An attacker with
online access to an unpatched system could exploit this vulnerability to
obtain private key information.

CVSS Base Score: 5.3

CVSS Temporal Score: See

https://exchange.xforce.ibmcloud.com/vulnerabilities/108502

for the current score

CVSS Environmental Score*: Undefined

CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:N/A:N)

CVEID:

CVE-2015-3194

DESCRIPTION:

OpenSSL is vulnerable to a denial of service, caused by a NULL pointer
dereference when verifying certificates via a malformed routine. An attacker
could exploit this vulnerability using signature verification routines with
an absent PSS parameter to cause any certificate verification operation to
crash.

CVSS Base Score: 5.3

CVSS Temporal Score: See

https://exchange.xforce.ibmcloud.com/vulnerabilities/108503

for the current score

CVSS Environmental Score*: Undefined

CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:L)

CVEID:

CVE-2015-3195

DESCRIPTION:

OpenSSL could allow a remote attacker to obtain sensitive information, caused
by a memory leak in a malformed X509_ATTRIBUTE structure. An attacker could
exploit this vulnerability to obtain CMS data and other sensitive
information.

CVSS Base Score: 5.3

CVSS Temporal Score: See

https://exchange.xforce.ibmcloud.com/vulnerabilities/108504

for the current score

CVSS Environmental Score*: Undefined

CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:N/A:N)

CVEID:

CVE-2015-3196

DESCRIPTION:

OpenSSL is vulnerable to a denial of service, caused by a race condition when
PSK identity hints are received by a multi-threaded client and the SSL_CTX
structure is updated with the incorrect value. An attacker could exploit this
vulnerability to possibly corrupt memory and cause a denial of service.

CVSS Base Score: 3.7

CVSS Temporal Score: See

https://exchange.xforce.ibmcloud.com/vulnerabilities/108505

for the current score

CVSS Environmental Score*: Undefined

CVSS Vector: (CVSS:3.0/AV:N/AC:H/PR:N/UI:N/S:U/C:N/I:N/A:L)

CVEID:

CVE-2015-1794

DESCRIPTION:

OpenSSL is vulnerable to a denial of service, caused by an error when a
client receives a ServerKeyExchange for an anonymous DH ciphersuite with the
value of p set to 0. An attacker could exploit this vulnerability to trigger
a segfault and cause a denial of service.

CVSS Base Score: 3.7

CVSS Temporal Score: See

https://exchange.xforce.ibmcloud.com/vulnerabilities/108539

for the current score

CVSS Environmental Score*: Undefined

CVSS Vector: (CVSS:3.0/AV:N/AC:H/PR:N/UI:N/S:U/C:N/I:N/A:L)
