Category Security Release Phase Resolved 6804996, 6804997, 6804998, 6804999 Date of Resolved Release 24-Mar-2009 Buffer overflow vulnerabilities in the Java Runtime Environment (JRE) with processing image files and fonts may allow privileges to be escalated: 1. Impact CR 6804996: A buffer overflow vulnerability in the Java Runtime Environment with processing PNG images may allow an untrusted Java Web Start application to escalate privileges. For example, an untrusted application may grant itself permissions to read and write local files or execute local applications that are accessible to the user running the untrusted application. CR 6804997: A buffer overflow vulnerability in the Java Runtime Environment with processing GIF images may allow an untrusted Java Web Start application to escalate privileges. For example, an untrusted application may grant itself permissions to read and write local files or execute local applications that are accessible to the user running the untrusted application. CR 6804998: A buffer overflow vulnerability in the Java Runtime Environment with processing GIF images may allow an untrusted applet or Java Web Start application to escalate privileges. For example, an untrusted applet may grant itself permissions to read and write local files or execute local applications that are accessible to the user running the untrusted applet. CR 6804999: A buffer overflow vulnerability in the Java Runtime Environment with processing fonts may allow an untrusted applet or Java Web Start application to escalate privileges. For example, an untrusted applet may grant itself permissions to read and write local files or execute local applications that are accessible to the user running the untrusted applet.
