Vulnerability Details
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-2015-3196
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-2016-0702
DESCRIPTION:
OpenSSL could allow a local attacker to obtain sensitive information, caused
by a side-channel attack against a system based on the Intel Sandy-Bridge
microarchitecture. An attacker could exploit this vulnerability to recover
RSA keys.
CVSS Base Score: 2.9
CVSS Temporal Score: See
https://exchange.xforce.ibmcloud.com/vulnerabilities/111144
for the current score
CVSS Environmental Score*: Undefined
CVSS Vector: (CVSS:3.0/AV:L/AC:H/PR:N/UI:N/S:U/C:L/I:N/A:N)
