Vulnerabilities
Vulnerability Details
CVEID:
CVE-2000-1254
DESCRIPTION:
OpenSSL could allow a remote attacker to obtain sensitive information, caused
by the improper handling of C bitwise-shift operations that exceed the size
of an expression by crypto/rsa/rsa_gen.c. An attacker could exploit this
vulnerability to defeat cryptographic protection mechanisms and decrypt data.
CVSS Base Score: 7.5
CVSS Temporal Score: See
https://exchange.xforce.ibmcloud.com/vulnerabilities/113136
for the current score
CVSS Environmental Score*: Undefined
CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N)
CVEID:
CVE-2016-2177
DESCRIPTION:
OpenSSL is vulnerable to a denial of service, caused by the incorrect use of
pointer arithmetic for heap-buffer boundary checks. By leveraging unexpected
malloc behavior, a remote attacker could exploit this vulnerability to
trigger an integer overflow and cause the application to crash.
CVSS Base Score: 5.9
CVSS Temporal Score: See
https://exchange.xforce.ibmcloud.com/vulnerabilities/113890
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:H)
CVEID:
CVE-2016-2180
DESCRIPTION:
OpenSSL is vulnerable to a denial of service, caused by an out-of-bounds read
in the TS_OBJ_print_bio function. A remote attacker could exploit this
vulnerability using a specially crafted time-stamp file to cause the
application to crash.
CVSS Base Score: 7.5
CVSS Temporal Score: See
https://exchange.xforce.ibmcloud.com/vulnerabilities/115829
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-2016-2183
DESCRIPTION:
OpenSSL could allow a remote attacker to obtain sensitive information, caused
by an error in the DES/3DES cipher, used as a part of the SSL/TLS protocol.
By capturing large amounts of encrypted traffic between the SSL/TLS server
and the client, a remote attacker able to conduct a man-in-the-middle attack
could exploit this vulnerability to recover the plaintext data and obtain
sensitive information. This vulnerability is known as the SWEET32 Birthday
attack.
CVSS Base Score: 3.7
CVSS Temporal Score: See
https://exchange.xforce.ibmcloud.com/vulnerabilities/116337
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-2016-3036
DESCRIPTION:
IBM Cognos TM1 is vulnerable to a denial of service, caused by a stack-based
buffer overflow when parsing packets. A remote attacker could exploit this
vulnerability to cause a denial of service.
CVSS Base Score: 7.5
CVSS Temporal Score: See
https://exchange.xforce.ibmcloud.com/vulnerabilities/114612
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-2016-3037
DESCRIPTION:
IBM Cognos TM1 provides a service to return the victim's password with a
valid session key. An authenticated attacker with user interaction could
obtain this sensitive information.
CVSS Base Score: 5.7
CVSS Temporal Score: See
https://exchange.xforce.ibmcloud.com/vulnerabilities/114613
for the current score
CVSS Environmental Score*: Undefined
CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:L/UI:R/S:U/C:H/I:N/A:N)
CVEID:
CVE-2016-3038
DESCRIPTION:
IBM Cognos TM1 is vulnerable to cross-site scripting. This vulnerability
allows users to embed arbitrary JavaScript code in the Web UI thus altering
the intended functionality potentially leading to credentials disclosure
within a trusted session.
CVSS Base Score: 5.4
CVSS Temporal Score: See
https://exchange.xforce.ibmcloud.com/vulnerabilities/114614
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-2016-3092
DESCRIPTION:
Apache Tomcat is vulnerable to a denial of service, caused by an error in the
Apache Commons FileUpload component. By sending file upload requests, an
attacker could exploit this vulnerability to cause the server to become
unresponsive.
CVSS Base Score: 5.3
CVSS Temporal Score: See
https://exchange.xforce.ibmcloud.com/vulnerabilities/114336
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-2016-3485
DESCRIPTION:
An unspecified vulnerability in Oracle Java SE and Java SE Embedded related
to the Networking component has no confidentiality impact, low integrity
impact, and no availability impact.
CVSS Base Score: 2.9
CVSS Temporal Score: See
https://exchange.xforce.ibmcloud.com/vulnerabilities/115273
for the current score
CVSS Environmental Score*: Undefined
CVSS Vector: (CVSS:3.0/AV:L/AC:H/PR:N/UI:N/S:U/C:N/I:L/A:N)
CVEID:
CVE-2016-6304
DESCRIPTION:
OpenSSL is vulnerable to a denial of service, caused by multiple memory leaks
in t1_lib.c during session renegotiation. By sending an overly large OCSP
Status Request extension, a remote attacker could exploit this vulnerability
to consume all available memory resources.
CVSS Base Score: 7.5
