Gregory" <ggregory@...che.org> To: oss-security@...ts.openwall.com Subject: CVE-2022-42920: Apache Commons BCEL prior to 6.6.0 allows producing arbitrary bytecode via out-of-bounds writing Description: Apache Commons BCEL has a number of APIs that would normally only allow changing specific class characteristics. However, due to an out-of-bounds writing issue, these APIs can be used to produce arbitrary bytecode. This could be abused in applications that pass attacker-controllable data to those APIs, giving the attacker more control over the resulting bytecode than otherwise expected. Update to Apache Commons BCEL 6.6.0. This issue is being tracked as BCEL-363 Credit: Reported by Felix Wilhelm (Google); GitHub pull request to Apache Commons BCEL #147 by Richard Atkins (https://github.com/rjatkins); PR derived from OpenJDK (https://github.com/openjdk/jdk11u/) commit 13bf52c8d876528a43be7cb77a1f452d29a21492 by Aleksei Voitylov and RealCLanger (Christoph Langer https://github.com/RealCLanger)
