CVE-2019-10245 : What You Need to Know
Learn about CVE-2019-10245 affecting Eclipse OpenJ9 prior to 0.14.0. Understand the impact, affected systems, exploitation, and mitigation steps to secure your systems.
Eclipse OpenJ9 prior to version 0.14.0 had a vulnerability in the Java bytecode verifier that allowed a method to execute beyond the bytecode array, leading to crashes. This issue was resolved in version 0.14.0.
Understanding CVE-2019-10245
Before the release of Eclipse OpenJ9 version 0.14.0, there was an issue with the Java bytecode verifier that mistakenly permitted a method to continue executing beyond the end of the bytecode array, resulting in crashes. This problem has been addressed in Eclipse OpenJ9 v0.14.0, which now properly identifies and rejects the attempted class load in such cases.
What is CVE-2019-10245?
In Eclipse OpenJ9 prior to the 0.14.0 release, the Java bytecode verifier incorrectly allows a method to execute past the end of the bytecode array causing crashes. Eclipse OpenJ9 v0.14.0 correctly detects this case and rejects the attempted class load.
The Impact of CVE-2019-10245
- The vulnerability could lead to crashes in affected systems running Eclipse OpenJ9 versions prior to 0.14.0.
