The class file parser in IBM Java before 1.4.2 SR13 FP9, as used in IBM Runtimes for Java Technology 5.0.0 before SR13 and 6.0.0 before SR10

The class file parser in IBM Java before 1.4.2 SR13 FP9, as used in IBM Runtimes for Java Technology 5.0.0 before SR13 and 6.0.0 before SR10, allows remote authenticated users to cause a denial of service (JVM segmentation fault, and possibly memory consumption or an infinite loop) via a crafted attribute length field in a class file, which triggers a buffer over-read.

No known public exploit

No public exploit has been observed yet. That doesn't mean you're safe, only that the bar is a little higher.

Research context

For pentesters and researchers: attack profile, score disagreement, timeline, patch commits, credits, variant and chain candidates, bug bounty scope. All derived from existing data; no exploit code.

Variant candidates

Same product, same weakness class, within 18 months. If the patch missed the root cause, the sibling bug is here.

No nightly-computed relations.

Chain candidates

An authentication bypass and a privilege-requiring bug in the same product, published close together: combined they may become an unauthenticated path.
