AI-suggested

Users should upgrade Apache Commons BCEL to version 6.13.0 or later, which fixes the symbolic name validation issue. Since this is a library vulnerability, ensure that OpenJDK 8 distributions incorporate this fixed BCEL version. No other mitigations are specified.

Description

A vulnerability in Apache Commons BCEL used by OpenJDK 8 allows symbolic names to be mapped incorrectly to classes. This occurs because BCEL caches attacker-controlled classes under their self-declared names without validating the requested name, enabling subsequent lookups and verification to reference a different class. The issue affects multiple OpenJDK 8 versions and is fixed in Apache Commons BCEL version 6.13.0.
