Summary
There are multiple security vulnerabilities that have been fixed in the IBM
Security Privileged Identity Manager Product
Vulnerability Details
CVEID:
CVE-2016-0366
DESCRIPTION:
IBM Security Identity Manager Virtual Appliance could allow a remote attacker
to obtain sensitive information due to weak encryption using man in the
middle techniques.
CVSS Base Score: 3.7
CVSS Temporal Score: See
https://exchange.xforce.ibmcloud.com/vulnerabilities/112071
for the current score
CVSS Environmental Score*: Undefined
CVSS Vector: (CVSS:3.0/AV:N/AC:H/PR:N/UI:N/S:U/C:L/I:N/A:N)
CVEID:
CVE-2015-8629
DESCRIPTION:
MIT Kerberos could allow a remote authenticated attacker to obtain sensitive
information, caused by a null termination in the xdr_nullstring() function.
By sending specially-crafted data, an attacker could exploit this
vulnerability to obtain sensitive information from the memory.
CVSS Base Score: 4.3
CVSS Temporal Score: See
https://exchange.xforce.ibmcloud.com/vulnerabilities/110395
for the current score
CVSS Environmental Score*: Undefined
CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:L/UI:N/S:U/C:L/I:N/A:N)
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-2016-0799
DESCRIPTION:
OpenSSL could allow a remote attacker to obtain sensitive information, caused
by a memory error in the BIO_*printf() functions. An attacker could exploit
this vulnerability using specially crafted data to trigger an out-of-bounds
read.
CVSS Base Score: 3.7
CVSS Temporal Score: See
https://exchange.xforce.ibmcloud.com/vulnerabilities/111143
for the current score
CVSS Environmental Score*: Undefined
CVSS Vector: (CVSS:3.0/AV:N/AC:H/PR:N/UI:N/S:U/C:L/I:N/A:N)
CVEID:
CVE-2016-2105
DESCRIPTION:
OpenSSL is vulnerable to a heap-based buffer overflow, caused by improper
bounds checking by the EVP_EncodeUpdate() function. By sending an overly long
argument, a remote attacker could overflow a buffer and execute arbitrary
code on the system or cause the application to crash.
CVSS Base Score: 5.6
CVSS Temporal Score: See
https://exchange.xforce.ibmcloud.com/vulnerabilities/112855
for the current score
CVSS Environmental Score*: Undefined
CVSS Vector: (CVSS:3.0/AV:N/AC:H/PR:N/UI:N/S:U/C:L/I:L/A:L)
CVEID:
CVE-2016-2106
DESCRIPTION:
OpenSSL is vulnerable to a heap-based buffer overflow, caused by improper
bounds checking by the EVP_EncryptUpdate() function. By sending an overly
long argument, a remote attacker could overflow a buffer and execute
arbitrary code on the system or cause the application to crash.
CVSS Base Score: 5.6
CVSS Temporal Score: See
https://exchange.xforce.ibmcloud.com/vulnerabilities/112856
for the current score
CVSS Environmental Score*: Undefined
CVSS Vector: (CVSS:3.0/AV:N/AC:H/PR:N/UI:N/S:U/C:L/I:L/A:L)
CVEID:
CVE-2016-2107
DESCRIPTION:
OpenSSL could allow a remote attacker to obtain sensitive information, caused
by an error when the connection uses an AES CBC cipher and the server support
AES-NI. A remote user with the ability to conduct a man-in-the-middle attack
could exploit this vulnerability via the POODLE (Padding Oracle On Downgraded
Legacy Encryption) attack to decrypt traffic.
CVSS Base Score: 4.3
CVSS Temporal Score: See
https://exchange.xforce.ibmcloud.com/vulnerabilities/112854
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:N/A:N)
CVEID:
CVE-2016-2109
DESCRIPTION:
OpenSSL is vulnerable to a denial of service, caused by a memory allocation
error. By reading specially crafted ASN.1 data from a BIO using functions
such as d2i_CMS_bio(), an attacker could exploit this vulnerability to
consume all available resources and exhaust memory.
CVSS Base Score: 5.3
CVSS Temporal Score: See
https://exchange.xforce.ibmcloud.com/vulnerabilities/112857
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-2016-2842
DESCRIPTION:
OpenSSL is vulnerable to a denial of service, caused by the failure to verify
that a certain memory allocation succeeds by the doapr_outch function. A
remote attacker could exploit this vulnerability using a specially crafted
string to cause an out-of-bounds write or consume an overly large amount of
resources.
CVSS Base Score: 7.5
CVSS Temporal Score: See
https://exchange.xforce.ibmcloud.com/vulnerabilities/111304
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:H)
CVEID:
CVE-2016-2996
DESCRIPTION:
IBM Security Privileged Identity Manager Virtual Appliance could allow an
authenticated user to append lines to any file on the system due to an error
with input validation.
CVSS Base Score: 6.5
CVSS Temporal Score: See
https://exchange.xforce.ibmcloud.com/vulnerabilities/114150
