Raphael Geissert discovered multiple heap-based buffer overflows in OpenJPEG. If a specially-crafted image were opened by an application linked against OpenJPEG, it could cause the application to crash or, potentially, execute arbitrary code with the privileges of the user running the application. These issues only affected the version of OpenJPEG as shipped in Red Hat Enterprise Linux 6 and EPEL 5 (version 1.3).
