Vulnerability Details
CVEID:
CVE-2016-0327
DESCRIPTION:
IBM Security Identity Manager Virtual Appliance could allow a local user to
injection commands that would be executed with administrator privileges.
CVSS Base Score: 8.4
CVSS Temporal Score: See
https://exchange.xforce.ibmcloud.com/vulnerabilities/111643
for the current score
CVSS Environmental Score*: Undefined
CVSS Vector: (CVSS:3.0/AV:L/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H)
CVEID:
CVE-2016-0797
DESCRIPTION:
OpenSSL is vulnerable to a denial of service, caused by a NULL pointer
dereference in the BN_hex2bn/BN_dec2bn() function. An attacker could exploit
this vulnerability using specially crafted data to cause a denial of service.
CVSS Base Score: 3.7
CVSS Temporal Score: See
https://exchange.xforce.ibmcloud.com/vulnerabilities/111142
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-2016-0800
DESCRIPTION:
OpenSSL could allow a remote attacker to bypass security restrictions. By
using a server that supports SSLv2 and EXPORT cipher suites as a
Bleichenbacher RSA padding oracle, an attacker could exploit this
vulnerability to decrypt TLS sessions between clients and non-vulnerable
servers. This vulnerability is also known as the DROWN attack.
CVSS Base Score: 7.4
CVSS Temporal Score: See
https://exchange.xforce.ibmcloud.com/vulnerabilities/111139
for the current score
CVSS Environmental Score*: Undefined
CVSS Vector: (CVSS:3.0/AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:H/A:N)
CVEID:
CVE-2016-0705
DESCRIPTION:
OpenSSL is vulnerable to a denial of service, caused by a double-free error
when parsing DSA private keys. An attacker could exploit this vulnerability
to corrupt memory and cause a denial of service.
CVSS Base Score: 3.7
CVSS Temporal Score: See
https://exchange.xforce.ibmcloud.com/vulnerabilities/111140
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-2015-3197
DESCRIPTION:
OpenSSL could allow a remote attacker to conduct man-in-the-middle attacks,
caused by an error related to the negotiation of disabled SSLv2 ciphers by
malicious SSL/TLS clients. An attacker could exploit this vulnerability to
conduct man-in-the-middle attacks.
CVSS Base Score: 5.4
CVSS Temporal Score: See
https://exchange.xforce.ibmcloud.com/vulnerabilities/110235
for the current score
CVSS Environmental Score*: Undefined
CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:N/UI:R/S:U/C:L/I:L/A:N)
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)
CVEID:
CVE-2016-0332
DESCRIPTION:
IBM Security Identity Manager Virtual Appliance uses an inadequate account
lockout setting that could allow a remote attacker to brute force account
credentials.
CVSS Base Score: 5.3
CVSS Temporal Score: See
https://exchange.xforce.ibmcloud.com/vulnerabilities/111695
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:L/A:N)
CVEID:
CVE-2016-0324
DESCRIPTION:
IBM Security Privileged Identity Manager Virtual Appliance could allow an
authenticated attacker injection commands that would be executed by the
operating system with administrator privileges.
CVSS Base Score: 8.8
CVSS Temporal Score: See
https://exchange.xforce.ibmcloud.com/vulnerabilities/111640
for the current score
CVSS Environmental Score*: Undefined
CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H)
CVEID:
CVE-2016-0336
DESCRIPTION:
IBM Security Identity Manager Virtual Appliance is vulnerable to cross-site
scripting, caused by improper validation of user-supplied input. A remote
attacker could exploit this vulnerability using a specially-crafted URL to
execute script in a victim's Web browser within the security context of the
hosting Web site, once the URL is clicked. An attacker could use this
vulnerability to steal the victim's cookie-based authentication credentials.
CVSS Base Score: 5.4
CVSS Temporal Score: See
https://exchange.xforce.ibmcloud.com/vulnerabilities/111737
for the current score
CVSS Environmental Score*: Undefined
CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:L/UI:R/S:C/C:L/I:L/A:N)
CVEID:
CVE-2016-0335
DESCRIPTION:
IBM Security Identity Manager Virtual Appliance is vulnerable to cross-site
request forgery, caused by improper validation of user-supplied input. By
persuading an authenticated user to visit a malicious Web site, a remote
attacker could send a malformed HTTP request. An attacker could exploit this
vulnerability to perform cross-site scripting attacks, Web cache poisoning,
and other malicious activities.
CVSS Base Score: 8.8
CVSS Temporal Score: See
https://exchange.xforce.ibmcloud.com/vulnerabilities/111736
for the current score
CVSS Environmental Score*: Undefined
CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H)
CVEID:
CVE-2016-0787
DESCRIPTION:
libssh2 could provide weaker than expected security, caused by a type
confusion error during the SSHv2 handshake resulting in the generation of a
reduced amount of random bits for Diffie-Hellman. An attacker could exploit
this vulnerability using the truncated Diffie-Hellman secret to launch
further attacks on the system.
CVSS Base Score: 6.5
CVSS Temporal Score: See
https://exchange.xforce.ibmcloud.com/vulnerabilities/111562
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:L/A:N)
CVEID:
CVE-2016-1950
DESCRIPTION:
Mozilla Firefox is vulnerable to a heap-based buffer overflow, caused by
improper bounds checking when the Network Security Services (NSS) libraries
parsed certain ASN.1 structures. By persuading a victim to open a specially
crafted certificate, a remote attacker could overflow a buffer and execute
arbitrary code on the system or cause the application to crash.
CVSS Base Score: 8.8
