Software vendors provide crash reporter to automatically collect crash reports from users to facilitate efficient handling of crash of their products. The crash reporter should be secure and reliable due to the fact that it handles sensitive information, such as core dump that captures the CPU context and memory contents of the crashed program, and helps to address the issue of crashed program. Unfortunately, several security flaws have been reported to the various crashing reporter for Windows, Mac OS X, Linux, Mozilla, etc. In this talk, Seong-Joong Kim will address security problems that reside in popular open source project for crash reporter. After auditing the source code, he found several flaws in the project, caused by unrestricted file upload vulnerability. When it allows the upload of an arbitrary crash report and the attacker may overflow a buffer on heap-memory, unhandled exception or cause resource exhaustion, which may lead to dreadful consequences. He will demonstrate those attacks and share the steps for improving security of the crash reporter.
