Loop Versioning Bug in Eclipse OpenJ9 by Eclipse Foundation

CVE-2019-11775

What is CVE-2019-11775?

Eclipse OpenJ9 versions before 0.15 suffer from a loop versioning vulnerability. This issue arises when the loop versioner fails to privatize a value moved out of the loop, leading to potential read out of array bounds and other unintended consequences. Specifically, when conditions are relocated from the loop without proper value privatization, subsequent iterations may utilize modified field values without re-evaluating the original conditions. This oversight can introduce various instability issues within applications utilizing the affected versions.
