Security Bulletin: IBM Tivoli Directory Integrator can be affected by vulnerabilities in the IBM Java Runtime Environment (CVE-2013-0440, CVE-2013-0443, CVE-2013-0169)

Flash (Alert)


Abstract

CVE-2013-0440 - Unspecified vulnerability in IBM Java Runtime Environment allows remote attackers to affect availability via vectors related to JSSE.

CVE- 2013-0443 - Unspecified vulnerability in IBM Java Runtime Environment allows remote attackers to affect confidentiality and integrity via vectors related to JSSE

CVE-2013-0169 - The Transport Layer Security protocol does not properly consider timing side-channel attacks, which allows remote attackers to conduct distinguishing attacks and plain-text recovery attacks via statistical analysis of timing data for crafted packets, aka the "Lucky Thirteen" issue.

VULNERABILITY DETAILS:

DESCRIPTION:

CVE-2013-0440
The current implementation of the Java Secure Socket Extension {“JSSE”} provider shipped with the IBM Java Runtime Environment may allow remote attackers to affect availability of the application.

The attack does not require local network access nor does it require authentication, but some degree of specialized knowledge and techniques are required. An exploit would not impact the confidentiality of information or the integrity of data, but could reduce performance / cause interruptions to availability.


CVEID:
CVE-2013-0440

CVSS Base Score: 5
CVSS Temporal Score: See http://xforce.iss.net/xforce/xfdb/81799
CVSS Environmental Score*: Undefined
CVSS Vector: (AV:N/AC:L/Au:N/C:N/I:N/A:P)




DESCRIPTION:

CVE-2013-0443
Unspecified vulnerability in IBM Java Runtime Environment allows remote attackers to affect confidentiality and integrity via vectors related to JSSE


The attack does not require local network access nor does it require authentication, but a large degree of specialized knowledge and techniques are required. An exploit may have a limited impact the confidentiality of information and the integrity of data, but the availability of the system would not be compromised.

CVEID:
CVE-2013-0443

CVSS Base Score: 4
CVSS Temporal Score: See http://xforce.iss.net/xforce/xfdb/81801
CVSS Environmental Score*: Undefined
CVSS Vector: (AV:N/AC:H/Au:N/C:P/I:P/A:N)




DESCRIPTION:

CVE-2013-0169
A weakness in the handling of cipher-block chaining (CBC) ciphersuites in Secure Sockets Layer (SSL), Transport Layer Security (TLS) and Datagram Transport Layer Security (DTLS) could lead to plaintext recovery of sensitive information by exploiting timing differences arising during message authentication codes (MAC) processing. The CVSS score is based on IBM X-Force rankings, which sets the access complexity for this vulnerability as Medium.

The attack does not require local network access nor does it require authentication, but some degree of specialized knowledge and techniques are required. An exploit may have a limited impact on the confidentiality of information but neither the integrity of data nor the availability of the system would be compromised.

CVEID:
CVE-2013-0169

CVSS Base Score: 4.3
CVSS Temporal Score: See http://xforce.iss.net/xforce/xfdb/81902
CVSS Environmental Score*: Undefined
CVSS Vector: (AV:N/AC:M/Au:N/C:P/I:N/A:N)
