IBM Runtimes for Java Technology class file parser denial of service

ibm-rjt-classfile-dos (65189) The risk level is classified as MediumMedium Risk

Description:

IBM Runtimes for Java Technology is vulnerable to a denial of service, caused by an error in the class file parser. A remote authenticated attacker could exploit this vulnerability using a specially-crafted class file containing an invalid attribute length field to cause a segmentation fault.IBM3

*CVSS:

Base Score: 3.5
  Access Vector: Network
  Access Complexity: Medium
  Authentication: Single
  Confidentiality Impact: None
  Integrity Impact: None
  Availability Impact: Partial
 
Temporal Score: 2.6
  Exploitability: Unproven
  Remediation Level: Official-Fix
  Report Confidence: Confirmed

Consequences:

Denial of Service

Remedy:

For Java 1.4.2:
Apply the latest Fix Pack (1.4.2 SR13 FP10 or later) or APAR PM42551. See References.

For Runtimes for Java Technology 5.0:
Apply the latest Fix Pack (5.0.0 SR13 or later) or APAR IZ89620. See References.

For Runtimes for Java Technology 6.0:
Apply the latest Fix Pack (6.0.0 SR10 or later) or APAR IZ89602. See References.
