Security Bulletin: IBM Rational Engineering Lifecycle Manager can be affected by vulnerabilities in the IBM JRE (CVE-2013-5802, CVE-2013-4002, CVE-2013-5825, CVE-2013-5372)

Security Bulletin


Summary

IBM Rational Engineering Lifecycle Manager is shipped with an IBM Java Runtime Environment (JRE) that is based on the Oracle JRE. Oracle has released October 2013 critical patch updates (CPU) which contain security vulnerability fixes. The IBM JRE has been updated to incorporate these fixes as well as ones specific to itself.

RELM is vulnerable to denial of service attacks triggered by specially crafted XML data. These vulnerabilities are in the XML parser and Java API for XML Processing (JAXP) of the IBM JRE used by RELM.

CVE ID: CVE-2013-5802

Description: JAXP is vulnerable to a denial of service attack via malformed XML.

The attack is remotely exploitable, has low access complexity, and authentication is not required. Partial compromises to confidentiality, integrity, and availability impact may occur.

CVSS Base Score: 7.5
CVSS Temporal Score: See http://xforce.iss.net/xforce/xfdb/87982 for the current score
CVSS Environmental Score*: Undefined
CVSS Vector: (AV/N:AC/L:Au/N:C/P:I/P:A/P)


CVE ID: CVE-2013-4002

Description: The Apache Xerces-J XML parser is vulnerable to a denial of service attack, which could cause the XML parser to consume CPU resources for several minutes before the data is eventually rejected.

The attack is remotely exploitable and does not 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 the availability of the system can be compromised.

CVSS Base Score: 7.1
CVSS Temporal Score: See http://xforce.iss.net/xforce/xfdb/85260 for the current score
CVSS Environmental Score*: Undefined
CVSS Vector: (AV/N:AC/M:Au/N:C/N:I/N:A/C)


CVE ID: CVE-2013-5825

Description: Malicious XML data can cause a denial of service attack via vectors related to JAXP.

The attack is remotely exploitable, has low access complexity, and authentication is not required. An exploit would not impact the confidentiality of information or the integrity of data, but reduced performance or availability interruptions may occur.

CVSS Base Score: 5
CVSS Temporal Score: See http://xforce.iss.net/xforce/xfdb/87988 for the current score
CVSS Environmental Score*: Undefined
CVSS Vector: (AV/N:AC/L:Au/N:C/N:I/N:A/P)


CVE ID: CVE-2013-5372 (Non-Oracle. Specific to IBM JRE/SDK)

Description: The XML4J parser is vulnerable to a denial of service attack, triggered by specially crafted XML data.

The attack is remotely exploitable and does not 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 reduced performance or availability interruptions may occur.

CVSS Base Score: 4.3
CVSS Temporal Score: See http://xforce.iss.net/xforce/xfdb/86662 for the current score
CVSS Environmental Score*: Undefined
CVSS Vector: (AV/N:AC/M:Au/N:C/N:I/N:A/P)
